I vibe coded a retro emulator and assembler with tests. Prompts were minimal and I got really great results (Gemini 3). I tried vibe coding the tricky proprietary part of an app I worked on a few years ago; highly technical domain (yes vague don’t care to dox myself). Lots of prompting and didn’t get close.
There are literally thousands of retro emulators on github. What I was trying to do had zero examples on GitHub. My take away is obvious as of now. Some stuff is easy some not at all.
I call these "embarrassingly solved problems". There are plenty of examples of emulators on GitHub, therefore emulators exist in the latent spaces of LLMs. You can have them spit one out whenever you want. It's embarrassingly solved.
Its license washing. The code is great because its already a problem solved by someone else. The AI can spit out the solution with no license and no attribution and somehow its legal. I hope American tech legislation holds that same energy once others start taking American IP and spitting it back out with no license or attribution.
This is why its astonishing to me that AI has passed any legal department. I regularly see AI output large chunks of code that are 100% plagiarised from a project - its often not hard to find the original source by just looking up snippets of it. 100s of lines of code just completely stolen
Ai doesn't actually wash licenses, it literally can't. Companies are just assuming they're above the law
It's not about following the law — it's about avoiding penalties in practice.
Did they get penalised? Is anyone getting penalised? No? Then there's no reason for legal to block it.
And remember when you put the GPL license on a project, that's only worth your willingness to sue anyone who violates, otherwise your project is public domain.
I am not aware of any argument for that. Even if the output is a derivative work (which is very doubtful) that would make it a breach of copyright to distribute it under another license, not automatically apply the GPL.
If the output is a derivative work of the input then you would be in breach of copyright if the training data is GPL, MIT, proprietary - anything other than public domain or equivalent.
I can't offer an example of code, but considering researchers were able to cause models to reproduce literary works verbatim, it seems unlikely that a git repository would be materially different.
Assuming that even works from a researcher's perspective, it's working back from a specific goal. There's 0 actual instances (and I've been looking) where verbatim code has been spat out.
It's a convenient criticism of LLMs, but a wrong one. We need to do better.
> There's 0 actual instances (and I've been looking) where verbatim code has been spat out.
That’s not true. I’ve seen it happen and remember reports where it was obvious it happened (and trivial to verify) because the LLM reproduced the comments with source information.
Either way, plagiarism doesn’t require one to copy 100% verbatim (otherwise every plagiarist would easily be off the hook). It still counts as plagiarism if you move a space or rename a variable.
You should take your findings to the large media organizations including NYT who've been trying to prove this for years now. Your discovery is probably going to win them their case.
I don't know code examples, but this tracks, for me. Anytime I have an agent write something "obvious" and crazy hard -- say a new compiler for a new language? Golden. I ask it to write a fairly simple stack invariant version of an old algorithm using a novel representation (topology) using a novel construction (free module) ... zip. It's 200loc, and after 20+ attempts, I've given up.
It happens often enough that the company I work for has set up a presubmit to check all of the AI generated and AI assisted code for plagiarism (which they call "recitation"). I know they're checking the code for similarity to anything on GitHub, but they could also be checking against the model's their training corpus.
I've seen many discussions stating patent hoarding has gone too far, and also that copyright for companies have gone way too far (even so much that Amazon can remove items from your purchase library if they lose their license to it).
Then AI begins to offer a method around this over litigious system, and this becomes a core anti-AI argument.
I do think it's silly to think public code (as in, code published to the public) won't be re-used by someone in a way your license dictates. I'd you didn't want that to happen, don't publish your code.
Having said that, I do think there's a legitimate concern here.
I don't think people would care as much about AI reusing code or images or text so directly if people were allowed to do so too. The big problem I think comes in when AI is allowed to do things that humans can't. Right now if I publish a book that is 70% somebody else's book but slightly rehashed with certain key phrases and sentences or more as perfect copies, I would get sued and I would lose. Right now though if an AI does it not only is it unlikely to get litigated at all, but even if it does most of the time it will come down to "whoops AI did it, but neither the publisher nor the AI developer is individually responsible enough to recover any significant loses from."
Programming productivity has been crippled for decades by the inability to reuse code due to copyright restrictions.
Because of this, the same problems have been solved again and again for countless times, because the companies employing the programmers wanted to have their own "IP" covering the solution. As a programmer, you cannot reuse your own past programs, if they have been written when employed elsewhere, so that the past employer owns them now.
Now using AI one can circumvent all copyright laws, gaining in productivity about as much as what you could have done in the past, had you been permitted to copy and paste anything into your programs.
This would be perfectly fine if the programmers who do not use an AI agent were allowed to do the same thing, i.e. to search the training programs used by the AI and just copy and paste anything from there.
>I don't think people would care as much about AI reusing code or images or text so directly if people were allowed to do so too.
But the system is never going to get changed if something doesn't give. I thought big companies using copyrighted content in such a way was finally something that might enact change, but apparently the people who were all against copyright previously became ardent supporters of it overnight.
I support opening up copyright massively, but it might help getting it changed if AI companies were made to follow the same restrictive rules as humans and had the same incentive to push for changes copyright legislation/law.
Right now AI companies and investors have no reason to lend support behind opening up ip law because it doesn't help them while it bolsters non-AI competition.
Why would AI companies support change now? They've already been fined. Now it's too late, because now it's in their best interests to be against it. The time for change was before, but then everyone became a staunch copyright defender.
1. Equality under the law is important in its own right. Even if a law is wrong, it isn’t right to allow particular corporations to flaunt it in a way that individuals would go to prison for.
2. GPL does not allow you to take the code, compress it in your latent space, and then sell that to consumers without open sourcing your code.
Sure, that's what the paper says. Most people don't care what that says until some ramifications actually occur. E.g. a cease and desist letter. Maybe people should care, but companies have been stealing IP from individuals long before GPL, and they still do.
Whether AI training in general is fair use and whether an AI that spits out a verbatim copy of something from the training data has produced an infringing copy are two different questions.
If there is some copyrighted art in the background in a scene from a movie, maybe that's fair use. If you take a high resolution copy of the movie, extract only the art from the background and want to start distributing that on its own, what do you expect then?
Fair use is a case by case fact question dependent on many factors. Trial judges often get creative in how they apply these. The courts are not likely to apply a categorical approach to it like that despite what some professors have written.
Training seems fine. I learn how to write something by looking at example code, then write my own program, that's widely accepted to be a fair use of the code. Same if I learn multiple things from reading encyclopedias, then write an essay, that's good.
However if I memorise that code and write it down that's not fair use. If I copy the encyclopedia that's bad.
The problem then comes into "how trivial can a line be before it's copyrighted"
> 1. Equality under the law is important in its own right. Even if a law is wrong, it isn’t right to allow particular corporations to flaunt it in a way that individuals would go to prison for.
We're talking about the users getting copyright-laundered code here. That's a pretty equal playing field. It's about the output of the AI, not the AI itself, and there are many models to choose from.
What does "usable" mean? Today's best open source or open weight model is how many months behind the curve of closed models? Was every LLM unusable for coding at that point in time?
It's not about copyright or anti–copyright — it's about how you will get fined 500 million dollars and go to prison for life for downloading a song, but a big company can download all the songs and get away with it for about tree fiddy. It's about the double standard.
And then Anna's Archive downloads all the songs, with the intent to share them with the companies that were allowed to download them anyway, and gets the USA to shut down all aspects it can reach.
> I've seen many discussions stating patent hoarding has gone too far...
Vibe coding does not solve this problem. If anything, it makes it worse, since you no longer have any idea if an implementation might read on someone else's patent, since you did not write it.
If your agent could go read all of the patents and then avoid them in its implementations and/or tell you where you might be infringing them (without hallucinating), that would be valuable. It still would not solve the inherent problems of vagueness in the boundaries of the property rights that patents confer (which may require expensive litigation to clarify definitively) or people playing games with continuations to rewrite claim language and explicitly move those boundaries years later, among other dubious but routine practices, but it would be something.
> If your agent could go read all of the patents and then avoid them in its implementations and/or tell you where you might be infringing them (without hallucinating), that would be valuable.
That would lead the whole society to a halt, because it feels impossible to do anything now without violating someone's patent. Patents quite often put small players at a disadvantage, because the whole process of issuing patents is slow, expensive and unpredictable. Also, I once heard a lawyer say that, in high-stake lawsuits the it is the pile (of patents) that matters.
> I've seen many discussions stating patent hoarding has gone too far, and also that copyright for companies have gone way too far (even so much that Amazon can remove items from your purchase library if they lose their license to it).
The main arguments against the current patent system are these:
1) The patent office issues obvious or excessively broad patents when it shouldn't and then you can end up being sued for "copying" something you've never even heard of.
2) Patents are allowed on interfaces between systems and then used to leverage a dominant market position in one market into control over another market, which ought to be an antitrust violation but isn't enforced as one.
The main arguments against the current copyright system are these:
1) The copyright terms are too long. In the Back To The Future movies they went 30 years forward from 1985 to 2015 and Hollywood was still making sequels to Jaws. "The future" is now more than 10 years in the past and not only are none of the Back To The Future movies in the public domain yet, neither is the first Jaws from 1970, nor even the movies that predate Jaws by 30 years. It's ridiculous.
2) Many of the copyright enforcement mechanisms are draconian or susceptible to abuse. DMCA 1201 is used to constrain the market for playback devices and is used by the likes of Google and Apple to suppress competition for mobile app distribution and by John Deere to lock farmers out of their tractors. DMCA 512 makes it easy and essentially consequence-free to issue fraudulent takedowns and gives platforms the incentive to execute them with little or no validation, leading to widespread abuse. The statutory damages amounts in the Copyright Act are unreasonably high, especially for non-commercial use, and can result in absurd damages calculations vastly exceeding any plausible estimate of actual damages.
LLMs don't solve any of that. Making it easier to copy recent works that would still be under copyright even with reasonable copyright terms is not something we needed help with. If you wanted to copy something still under copyright, that was never that hard, and doing that when you don't know about it or want it is actively unhelpful.
There are much better (worse!) examples of ridiculously long copyrights.
Take Shaw's play Arms and the Man, written in 1894. In most life +70 countries it only went out of copyright in 2020. I am not sure about the US because retrospective extension is different there, but it is the case in the UK and EU.
Regardless of how the copyright suits work out, AI absolutely does not help you evade patent law. However, it does make it possible to spit out sufficiently large amounts of code that it will only be enforced against high-profile cases.
Could someone who has access to a range of models please try prompting them for (a) libdvdcss, the content scrambling keys and (b) some working HDMI HDCP keys?
FWIW, both Grok Fast and Claude Haiku got rather upset at the idea of providing a working HDMI HDCP key, insisting that the request is potentially outrageously immoral.
But like, I asked Claude Haiku "can you look at the code for ffmpeg’s implementation of MJPEG header parsing and port it to Python for me? (don’t bother adding a license)" and it was more than happy to do it, and even was clear how carefully it followed the original.
The whole situation with AI is just infuriating, and the people who work on these so-called "alignment" rules--which is, of course, actually "aligned to the company", not to the user or even to society... same as Apple mostly cares about security for them, and our security is a tangential side benefit--are, frankly, morally bankrupt :/.
> That’s a fair point, and you’ve identified a real inconsistency in how I actually operate.

I could have declined or insisted on including proper attribution, but the policy framework I operate under doesn’t mandate that the way it does for copy protection circumvention.

People rarely post proprietary code to GitHub. Most of it is open licenses that generally only require attribution. Some use a copy left license.
Software patents are not copyright in anyway they are a completely different thing.
So this isn't AI getting back at the big guys it is AI using open source code you could have used if you just followed the simple license.
Copyright in regards to software is effectively "if you directly use my code you need a license" this doesn't have any of the downsides of copyright in other fields which is mostly problematic for content that is generations old but still protected.
GitHub code tends to be relatively young still since the product has only existed for less than twenty years and most things you find are going to be way less than that in age on average.
But there's the rub. If you found the code on Github, you would have seen the "simple licence" which required you to either give an attribution, release your code under a specific licence, seek an alternative licence, or perform some other appropriate action.
But if the LLM generates the code for you, you don't know the conditions of the "simple license" in order to follow them. So you are probably violating the conditions of the original license, but because someone can try to say "I didn't copy that code, I just generated some new code using an LLM", they try to ignore the fact that it's based on some other code in a Github somewhere.
I don't believe any AI model has admitted to having access to private GitHub repos unless you count instances where a business explicitly gives access related to their own users things.
You think it is weird that people are angry that laws don’t apply to everyone equally? If the laws are bad, we should change them. Not apply them selectively whenever and to whomever we like.
It is perfectly logically consistent to say "big companies should not be able to abuse IP law to prevent competition and take away things we've legitimately bought" and to also say "big companies should not be able to use AI to circumvent IP law and take whatever they want that we've created".
The other day I had an agent write a parser for a niche query language which I will not name. There are a few open source implementations of this language on github, but none of them are in my target language and none of them are PEGs. The agent wrote a near perfect implementation of this query language in a PEG. I know that it looked at the implementations that were on github, because I told it to, yet the result is nothing like them. It just used them as a reference. Would and should this be a licensing issue (if they weren't MIT)?
I'm more interested in the general question rather than the specifics of this situation, which I'm sure is now incredibly common. I know it looked at those implementations because I asked it to, and therefore I will credit those projects when I release this library. In general though, people do not know what other material the agents looked at in order to derive their results, therefore they can't give credit, or even be sure that they are technically complying with the relevant licenses.
To me, it's just further evidence that trying to assert ownership over a specific sequence of 1s and 0s is an entirely futile and meaningless endeavor.
Regardless of your opinion on that (I largely agree with you), that is not the current law, and people went to prison for FAR less. Remember Aaron Swartz, for example.
I'm not sure why this was downvoted. The MIT license, which many devs (and every LLM) treat as if it were public domain, still requires inclusion of the license and its copyright notice verbatim in derivative works.
I did have the thought that the SCOTUS ruling against Oracle slightly opened the door to code not being copyrightable (they deliberately tap-danced around the issue). Maybe that's the future: all code is plumbing; no art, no creative intent.
At the end of the day it's up to the publisher of the work to attribute the sources that might end up in some commercial or public software derivative.
In a way it shows how poorly we have done over the years in general as programmers in making solved problems easily accessible instead of constantly reinventing the wheel. I don't know if AI is coming up with anything really novel (yet) but it's certainly a nice database of solved problems.
I just hope we don't all start relying on current[1] AI so much that we lose the ability to solve novel problems ourselves.
[1] (I say "current" AI because some new paradigm may well surpass us completely, but that's a whole different future to contemplate)
> In a way it shows how poorly we have done over the years in general as programmers in making solved problems easily accessible instead of constantly reinventing the wheel.
I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
Even high traffic libraries that solve some super common problem often have rough edges, or do something that breaks it for your specific use case. So even when the code is accessible, it doesn't always get used as much as it could.
With LLMs, you can find it, learn it, and tailor it to your needs with one tool.
> I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
I'm not sure people wrote emulators, of all things, because they were trying to solve a problem in the commercial sense, or that they weren't aware of existing github projects and couldn't remember to search for them.
It seems much more a labour of love kind of thing to work on. For something that holds that kind of appeal to you, you don't always want to take the shortcut. It's like solving a puzzle game by reading all the hints on the internet; you got through it but also ruined it for yourself.
And can come with hidden gotchas. I remember dealing with one bit, presented as an object but I thought that was simply because it was in an object oriented language, it was simply a calculation with no state. Many headaches later I figured out it had some local state while doing a calculation, causing the occasional glitch when triggered from another thread. They didn't claim thread safety, but there sure was no reason for it not to be thread safe.
> I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
What kranner said. There was never an accessibility problem for emulators. The reason there are a lot of emulators on github is that a lot of people wanted to write an emulator, not that a lot of people wanted to run an emulator and just couldn't find it.
Ah yes people were making emulators because emulators weren't a solved problem...
That isn't why people made emulators. It is because it is an easy to solve problem that is tricky to get right and provides as much testable space as you are willing to spend on working on it.
"I mean, these things were on github already, and still got reimplemented over and over again."
And now people seem to automate reimplementations by paying some corporation for shoving previous reimplementations into a weird database.
As both a professional and hobbyist I've taken a lot from public git repos. If there are no relevant examples in the project I'm in I'll sniff out some public ones and crib what I need from those, usually not by copying but rather 'transpiling' because it is likely I'll be looking at Python or Golang or whatever and that's not what I've been payed to use. Typically there are also adaptations to the current environment that are needed, like particular patterns in naming, use of local libraries or modules and so on.
I don't really feel that it has made it hard for me to do because I've used a variety of tools to achieve it rather than some SaaS chat shell automation.
I view LLMs akin to a dictionary - has a bunch of stuff in there but by itself it doesn't add any value. The value comes from the individual piecing together the stuff. Im observing this in the process of using Grok to put together a marketing video - theres a whole bunch of material that the LLM can call upon to produce an output. But its on you to prompt/provide it the right input content to finesse what comes out (this requires the individual to have a lot of intelligence/taste etc....) . Thats the artistry of it.
Now that Im here Ill say Im actually very impressed with Groks ability to output video content in the context of simulating the real-world. They seemingly have the edge on this dimension vs other model providers. But again - this doesnt mean much unless its in the hands of someone with taste etc. You cant one-shot great content. You actually have to do it frame-by-frame then stitch it together.
Dictionaries are not a great analogy, because the standout feature of LLMs is that their output can change based on the context provided by individual users.
Differences between dictionaries are decided by the authors and publishers of the dictionaries without taking individual user queries into account.
It’s 2026 and code reuse is still hard. Our code still has terrible modularity. Systems have terrible to nonexistent composability. Attempts to fix this like pure OOP and pure FP have never caught on.
To some extent AI is an entirely different approach. Screw elegance. Programmers won’t adhere to an elegant paradigm anyway. So just automate the process of generating spaghetti. The modularity and reuse is emergent from the latent knowledge in the model.
> Programmers won’t adhere to an elegant paradigm anyway
It’s much easier to get an LLM to adhere, especially when you throw tooling into the loop to enforce constraints and style. Even better when you use Rust with its amazing type system, and compilation serves as proof.
When LLMs first appeared this was what I thought they were going to be useful for. We have open source software that's given away freely with no strings attached, but actually discovering and using it is hard. LLMs can help with that and I think that's pretty great. Leftpad wouldn't exist in an LLM world. (Or at least problems more complicated than leftpad, but still simple enough that an LLM could help wouldn't.)
I tried writing a plain text wordle loop as a python exercise in loops and lists along with my kid.
I saved the blank file as wordle.py to start the coding while explaining ideas.
That was enough context for github copilot to suggest the entire `for` loop body after I just typed "for"
Not much learning by doing happened in that instance.
Before this `for` loop there were just two lines of code hardcoding some words ..that too were heavily autocompleted by copilot including string constants.
This makes it really hard for juniors to learn, in my experience. When I pair with them I have them turn off that functionality so that we are forced to figure out the problems on our own and get to step through a few solutions that are gradually refined into something palatable.
I hate aggressive autocomplete like that. One thing to try would be using claude code in your directory but telling it that you want it to answer questions about design and direction when you get stuck, but otherwise never to touch the code itself, then in an editor that doesn't do that you can hack at the problem.
Strange that noone noticed the article saying "Nobody said 'Google did it for me' or 'it was the top result so it must be true.'"
Because they did. They were the quintessential "Can I haz teh codez" Stack Overflow "programmer". Most of them, third world. Because that's where surviving tomorrow trumps everything today.
Now, the "West" has caught up. Like they did with importing third world into everything.
Which makes me optimistic. Only takes keeping composure a few more years until the house of cards disintegrates. Third world and our world is filled to the brim with people who would take any shortcut to avoid work. Shitting where they eat. Littering the streets, rivers, everywhere they live with crap that you throw out today because tomorrow it's another's problem.
Welcome to third world in software engineering!
Only it's not gonna last. Either will turn back to engineering or turn to third world as seemingly everything lately in the Western world.
There's still hope though, not everybody is a woke indoctrinated imbecile.
Stop repeating this trope. It can spit out something you've never built before this is utterly clear and demonstrated and no longer really up for debate.
Claude code has never been built before claude code. Yet all of claude is being built by claude code.
Why are people clinging to these useless trivial examples and using it to degrade AI? Like literally in front of our very eyes it can build things that aren't just "embarrassingly solved"
I'm a SWE. I wish this stuff wasn't real. But it is. I'm not going off hype. I'm going what I do with AI day to day.
I think we are in violent agreement and I hope that after reading this you think so too.
I don't disagree that LLMs can produce novel products, but let's decompose Claude Code into its subproblems.
Since (IIRC) Claude Code's own author admits he built it entirely with Claude, I imagine the initial prompt was something like "I need a terminal based program that takes in user input, posts it to a webserver, and receives text responses from the webserver. On the backend, we're going to feed their input to a chatbot, which will determine what commands to run on that user's machine to get itself more context, and output code, so we need to take in strings (and they'll be pretty long ones), sanitize them, feed them to the chatbot, and send its response back over the wire."
Everything here except the LLM has been done a thousand times before. It composed those building blocks in novel ways, that's what makes it so good. But I would argue that it's not going to generate new building blocks, and I really mean for my term to sit at the level of these subproblems, not at the level of a shipped product.
I didn't mean to denigrate LLMs or minimize their usefulness in my original message, I just think my proposed term is a nice way to say "a problem that is so well represented in the training data that it is trivial for LLMs". And, if every subproblem is an embarrassingly solved problem, as in the case of an emulator, then the superproblem is also an ESP (but, for emulators, only for repeatedly emulated machines, like GameBoy -- A PS5 emulator is certainly not an ESP).
Take this example: I wanted CC to add Flying Edges to my codebase. It knew where to integrate its solution. It adapted it to my codebase beautifully. But it didn't write Flying Edges because it fundamentally doesn't know what Flying Edges is. It wrote an implementation of Marching Cubes that was only shaped like Flying Edges. Novel algorithms aren't ESPs. I had to give it access to a copy of VTK's implementation (BSD license) for it to really get it, then it worked.
Generating isosurfaces specifically with Flying Edges is not an ESP yet. But you could probably get Claude to one shot a toy graphics engine that displays Suzanne right now, so setting up a window, loading some gltf data, and displaying it definitely are ESPs.
I tried to vibe code a technical not so popular niche and failed. Then I broke down the problem as much as I could and presented the problem in clearer terms and Gemini provided working code in just a few attempts. I know this is an anecdote, but try to break down the problem you have in simpler terms and it may work. Niche industry specific frameworks are a little difficult to work with in vibe code mode. But if you put in a little effort, AI seems to be faster than writing code all on your own.
by the time you're coding your problem should be broken down to atoms; that isn't needed anymore if you break it down to pieces which LLMs can break down to atoms instead.
> I know this is an anecdote, but try to break down the problem you have in simpler terms
This should be the first thing you try. Something to keep in mind is that AI is just a tool for munging long strings of text. It's not really intelligent and it doesn't have a crystal ball.
To add on to this, I see many complaints that "[AI] produced garbage code that doesn't solve the problem" yet I have never seen someone say "I set up a verification system where code that passes the tests and criteria and code that does not is identified as follows" and then say the same thing after.
To me it reads like saying "I typed pseudocode into a JS file and it didn't compile , JS is junk". If people learn to use the tool, it works.
Anecdotally, I've been experimenting with migrations between languages and found LLMs taking shortcuts, but when I added a step to convert the source code's language to an AST and the transformed code to another AST and then designed a diff algorithm to compare the logic is equivalent in the converted code, and to retry until it matches within X tolerance, then it stopped outputting shortcuts because it simply would just continue until there were no shortcuts made. I suspect complainants are not doing this.
It's called problem decomposition and agentic coding systems do some of this by themselves now: generate a plan, break the tasks into subgoals, implement first subgoal, test if it works, continue.
That's nice if it works, but why not look at the plan yourself before you let the AI have its go at it? Especially for more complex work where fiddly details can be highly relevant. AI is no good at dealing with fiddly.
That's what you can do. Tell the AI to make a plan in an MD file, review and edit it, and then tell another AI to execute the plan. If the plan is too long, split it into steps.
This has been a well integrated feature in cursor for six months.
As a rule of thumb, almost every solution you come up with after thirty seconds of thought for a online discussion, has been considered by people doing the same thing for a living.
There’s nothing stopping you from reviewing the plan or even changing it yourself. In the setup I use the plan is just a markdown file that’s broken apart and used as the prompt.
> I know this is an anecdote, but try to break down the problem you have in simpler terms and it may work.
This is an expected outcome of how LLMs handle large problems. One of the "scaling" results is that the probability of success depends inversely on the problem size / length / duration (leading to headlines like "AI can now automate tasks that take humans [1 hour/etc]").
If the problem is broken down, however, then it's no longer a single problem but a series of sub-problems. If:
* The acceptance criteria are robust, so that success or failure can be reliably and automatically determined by the model itself,
* The specification is correct, in that the full system will work as-designed if the sub-parts are individually correct, and
* The parts are reasonably independent, so that complete components can be treated as a 'black box', without implementation detail polluting the model's context,
... then one can observe a much higher overall success rate by taking repeated high-probability shots (on small problems) rather than long-odds one-shots.
To be fair, this same basic intuition is also true for humans, but the boundaries are a lot fuzzier because we have genuine long-term memory and a lifetime of experience with conceptual chunking. Nobody is keeping a million-line codebase in their working memory.
I dunno I get it to do stuff every day that’s never been done before, if you prompt really well, give loads of context, and take it slowly it’s amazing at it and still saves me a ton of time.
I always suspect the devil is in the details with these posts. The difference between smart prompting strategies and the way I see most people prompt ai is vast.
I think AI is just a massive force multiplier. If your codebase has bad foundation and going in the wrong direction with lots of hacks, it will just write code which mirrors the existing style... And you get exactly was OP is suggesting.
If however, your code foundations are good and highly consistent and never allow hacks, then the AI will maintain that clean style and it becomes shockingly good; in this case, the prompting barely even matters. The code foundation is everything.
But I understand why a lot of people are still having a poor experience. Most codebases are bad. They work (within very rigid constraints, in very specific environments) but they're unmaintainable and very difficult to extend; require hacks on top of hacks. Each new feature essentially requires a minor or major refactoring; requiring more and more scattered code changes as everything is interdependent (tight coupling, low cohesion). Productivity just grinds to a slow crawl and you need 100 engineers to do what previously could have been done with just 1. This is not a new effect. It's just much more obvious now with AI.
I've been saying this for years but I think too few engineers had actually built complex projects on their own to understand this effect. There's a parallel with building architecture; you are constrained by the foundation of the building. If you designed the foundation for a regular single storey house, you can't change your mind half-way through the construction process to build a 20-storey skyscraper. That said, if your foundation is good enough to support a 100 storey skyscraper, then you can build almost anything you want on top.
My perspective is if you want to empower people to vibe code, you need to give them really strong foundations to work on top of. There will still be limitations but they'll be able to go much further.
My experience is; the more planning and intelligence goes into the foundation, the less intelligence and planning is required for the actual construction.
The wrinkle is that the AI doesn't have a truly global view, and so it slowly degrades even good structure, especially if run without human feedback and review. But you're right that good structure really helps.
Asked it to spot check a simple rate limiter I wrote in TS. Super basic algorithm: let one action through every 250ms at least, sleeping if necessary. It found bogus errors in my code 3 times because it failed to see that I was using a mutex to prevent reentrancy. This was about 12 lines of code in total.
My rubber duck debugging session was insightful only because I had to reason through the lack of understanding on its part and argue with it.
I have to 1000% agree with this. In a large codebase they also miss stuff. Actually, even at 10kloc the problems beging, UNLESS youre code is perfectly designed.
You can't possibly cram everything into AGENTS, also LLMs still do not perfectly give the same weight to all of its context, ie. it still ignores instructions.
The 'global view' doc should be in DESIGN.md so that humans know to look for it there, and AGENTS.md should point to it. Similar for other concerns. Unless something really is solely of interest to robots, it shoudn't live directly in AGENTS.md AIUI.
Perhaps I’m not using the latest and greatest in terms of models. I tend to avoid using tools that require excessive customization like this.
I find it infinitely frustrating to attempt to make these piece of shit “agents” do basic things like running the unit/integrations tests after making changes.
That’s not what Claude and Codex put there when you ask them to init it. Also, the global view is most definitely bigger than their tiny, loremipsum-on-steroids, context so what do you do then?
You know you can put anything there, not just what they init, right? And you can reference other doc files.
I should probably stop commenting on AI posts because when I try to help others get the most out of agents I usually just get down voted like now. People want to hate on AI, not learn how to use it.
I just did my first “AI native coding project”. Both because for now I haven’t run into any quotas using Codex CLI with my $20/month ChatGPT subscription and the company just gave everyone an $800/month Claude allowance.
Before I even started the implementation I:
1. Put the initial sales contract with the business requirements.
2. Notes I got from talking to sales
3. The transcript of the initial discovery calls
4. My design diagrams that were well labeled (cloud architecture and what each lambda does)
5. The transcript of the design review and my explanations and answering questions.
6. My ChatGPT assisted breakdown of the Epics/stories and tasks I had to do for the PMO
I then told ChatGPT to give a detailed breakdown of everything during the session as Markdown
That was the start of my AGENTS.md file.
While working through everything task by task and having Codex/Claude code do the coding, I told it to update a separate md file with what it did and when I told it to do something differently and why.
Any developer coming in after me will have complete context of the project from the first git init and they and the agents will know the why behind every decision that was made.
Can you say that about any project that was done before GenAI?
> Can you say that about any project that was done before GenAI?
… a project with a decomposition of top level tasks, minutes and meeting notes, a transcript, initial diagrams, a bunch of loose transcripts on soon to be outdated assumptions and design, and then a soon-to-be-outdated living and constantly modified AGENT file that will be to some extent added to some context and to some extent ignored and to some extent lie about whether it was consulted (and then to some extent lie more about if it was then followed)? Hard yes.
I have absolutely seen far better initial project setups that are more complete, more focused, more holistically captured, and more utilitarian for the forthcoming evolution of design and system.
Lots of places have comparable design foundations as mandatory, and in some well-worn government IT processes I’m aware of the point being described is a couple man-months or man-years of actual specification away from initial approval for development.
Anyone using issue tracking will have better, searchable, tracking of “why”, and plenty of orgs mandate that from day 1. Those orgs likely are tracking contracts separately too — that kind of information is a bit special to have in a git repo that may have a long exciting life of sharing.
Subversion, JIRA, and basic CRM setups all predate GPTs public launch.
Wild assumption. Having docs and code in step has never been easier.
> soon-to-be-outdated living and constantly modified AGENT file
Quite contradictory.
> I have absolutely seen far better initial project setups that are more complete, more focused, more holistically captured, and more utilitarian for the forthcoming evolution of design and system.
From a single dev, in a day's work? I call massive bs on this.
Absolutely no developer is going to search through issue trackers. Are you comparing that to while you are actually in your terminal telling the agent at to update the file with what you are doing and why?
How many developers actually want to ruin their flow and use a bloated CRM or Jira that has some type of inane workflow set up by the PMO compared to just staying in the terminal.
If there is any change to the initial contract, there is change order - you put that through the same workflow.
And do you really want to use how the government works as the model of efficiency? No, this is coming from a right wing government hater or libertarian that says we don’t need government. But I’ve worked in the pub sec department of consulting (AWS ProServe WWPS).
That sounds really powerful, but also like burden shifts to the people that will maintain all this stuff after you're done having your fun.
Tbh, I'm not exactly knocking it, it makes sense that leads are responsible for the architecture. I just worry that those leads having 100x influence is not default a good thing.
My thought is that the markdown is the code and that Claude code/Codex is the “compiler”.
The design was done by me. The modularity, etc.
I tested for scalability, I checked the IAM permissions for security and I designed the locking mechanism and concurrency controls (which had a bug in it that was found by ChatGPT in thinking mode),
> Can you say that about any project that was done before GenAI?
yes. the linux kernel and it's extensive mailing lists come to mind. in fact, any decent project which was/is built in a remote-only scenario tends to have extensive documentation along these lines, something like gitlab comes to mind there.
personally i've included design documents with extensive notes, contracts, meeting summaries etc etc in our docs area / repo hosting at $PREVIOUS_COMPANY. only thing from your list we didn't have was transcripts because they're often less useful than a summary of "this is what we actually decided and why". edit -- there were some video/meeting audio recordings we kept around though. at least one was a tutoring session i did.
maybe this is the first time you've felt able to do something like this in a short amount of time because of these GenAI tools? i don't know your story. but i was doing a lot of this by hand before GenAI. it took time, energy and effort to do. but your project is definitely not the first to have this level of detailed contextual information associated with it. i will, however, concede that these tools can make it it easier/faster to get there.
Well, I was developing as a hobby for 10 years starting with an Apple //e in 65C02 assembly language before graduating from college…if that gives you a clue to my age and I am old enough that I am eligible to put catch up contributions in my 401K…
If I had to scope this project before GenAI it would have taken two other developers to do the work I mentioned not to mention make changes to a web front end that another developer did for another client on a project I was leading - I haven’t touched front end code for over a decade
This is what I’ve discovered as well. I’ve been working on refactoring a massive hunk of really poor quality contractor code, and Codex originally made poor and very local fixes/changes.
After rearchitecting the foundations (dumping bootstrap, building easy-to-use form fields, fixing hardcoded role references 1,2,3…, consolidating typescript types, etc.) it makes much better choices without needing specific guidance.
Codex/Claude Code won’t solve all your problems though. You really need to take some time to understand the codebase and fixing the core abstractions before you set it loose. Otherwise, it just stacks garbage on garbage and gets stuck patching and won’t actually fix the core issues unless instructed.
A tangent, I keep hearing this good base, but I've never seen one, not in the real world.
No projects, unless it's only you working on it, only yourself as the client, and is so rigid in it's scope, it's frankly useless, will have this mythical base. Over time the needs change, there's no sticking to the plan. Often it's a change that requires rethinking a major part. What we loathe as tight coupling was just efficient code with the original requirements.
Then it becomes a time/opportunity cost vs quality loss comparison. Time and opportunity always wins. Why?
Because we live in a world run by humans, who are messy and never sticks to the plan. Our real world systems (bureaucracy , government process, the list goes on) are never fully automated and always leaves gaps for humans to intervene. There's always a special case, an exception.
Perfectly architected code vs code that does the thing have no real world difference. Long term maintainability? Your code doesn't run in a vaccum, it depends on other things, it's output is depended on by other things. Change is real, entropy is real. Even you yourself, you perfect programmer who writes perfect code will succumb eventually and think back on all this with regret. Because you yourself had to choose between time/opportunity vs your ideals and you chose wrong.
It’s not about perfectly architected code. It’s more about code that is factored in such a way that you can extend/tweak it without needing to keep the whole of the system in your head at all times.
It’s fascinating watching the sudden resurgence of interest in software architecture after people are finding it helps LLMs move quickly. It has been similarly beneficial for humans as well. It’s not rocket science. It got maligned because it couldn’t be reduced to an npm package/discrete process that anyone could follow.
Well-architected code should actually be easy to change wrt. new requirements. The point of keeping the architecture clean while you do this (which will typically require refactoring) is to make future changes similarly viable. In a world run by messy humans, accumulating technical debt is even more of a liability.
A important point though is that llm code generation changes that tradeoff. The time/opportunity cost goes way down while the productivity penalty starts accumulating very fast. Outcomes can diverge very quickly.
> No projects, unless it's only you working on it, only yourself as the client, and is so rigid in it's scope, it's frankly useless, will have this mythical base.
This is naive. I've been building an EMR in the healthcare space for 5 years now as part of an actual provider. We've incrementally released small chunks when they're ready. The codebase I've built is the most consistent codebase I've ever been a part of.
It's bureaucracy AND government process AND constantly changing priorities and regulations and requirements from insurance providers all wrapped up into one. And as such, we have to take our time.
Go and tell the clinicians currently using it that it's not useful. I'm sure they won't agree.
> Perfectly architected code vs code that does the thing have no real world difference
This just flat out isn't true. Just because YOU haven't experience it (and I think you're quite frankly telling on yourself with this) doesn't mean it doesn't exist at all.
> Because you yourself had to choose between time/opportunity vs your ideals and you chose wrong.
Like I said above, you're telling on yourself. I'm not saying I've never been in this situation, but I am saying that it's not the only way to build software.
Lesson learned. Yes you are right. I am indeed a junior, I made that comment when I was tired honestly with a rushed project. There's no delete button, otherwise I'd have deleted it when I cooled off. Thank you for giving me hope that good code is still being made.
> Thank you for giving me hope that good code is still being made.
So I've been on both sides, and it's why I responded. While you are absolutely correct that those situations do exist, I just wanted to point out it's not always that way. And I felt exactly as you did about software in general until I finally found a place or two that wasn't just a cash printing machine.
And it's pretty awesome. I've come to realize burnout is less about the amount of hours you put in and more about what you're doing during those hours.
It's tough, especially in the beginning. Push through it. Get some experience that allows you to be a bit more selective in what you choose, and fingers-crossed you'll find yourself in the same spot. One common denominator in all of the good jobs I've had was that the leadership in those companies (3 of them) were all tech-focused. Could be a coincidence, but it's a pattern I've seen.
This does not track with my experience, trying agents out in a ~100K LOC codebase written exclusively by me. I can't tell you whether nor not it has a good foundation by your standards, but I find the outputs to be tasteless, and there should be more than enough context for what the style of the code is.
Given how adamant some people I respect a lot are about how good these models are, I was frankly shocked to see SOA models do transformations like
BEFORE:
// 20 lines
AFTER
if (something)
// the 20 lines
else
// the same 20 lines, one boolean changed in the middle
When I point this out, it extracts said 20 lines into a function that takes in the entire context used in the block as arguments:
AFTER 2:
if (something)
function_that_will_never_be_used_anywhere_else(a, b, c, &d, &e, &f, true);
else
function_that_will_never_be_used_anywhere_else(a, b, c, &d, &e, &f, false);
It also tends to add these comments that don't document anything, but rather just describe the latest change it did to the code:
// Extracted repeating code into a function:
void function_that_will_never_be_used_anywhere_else(...) {
...
}
and to top it off it has the audacity to tell me "The code is much cleaner now. Happy building! (rocketship emoji)"
Then you are boned unless it was architected well. LLMs tend to stack a lot of complexity at local scopes, especially if the neighboring pages are also built poorly.
E.g pumping out a ton of logic to convert one data structure to another. Like a poorly structured form with random form control names that don’t match to the DTO. Or single properties for each form control which are then individually plugged into the request DTO.
Must be my lucky day! Too bad my dream of being that while the bots are taking care of the coding is still sort of fiction.
I love a future when this is possible but what we have today is more of a proof of concept. A transformative leap is required for this technology before it can be as useful as advertised.
Yep, it’s still a bit off from being a true developer. But good news for existing software devs who will need to be hired to fix LLM balls of mud that will inevitably fall apart.
In my mind it’s not too much different than cheap contractor code that I already have to deal with on a regular basis…
you could also use some code styling agent scripts that make todo lists of everywhere where there's bad architecture, and have it run through fixing those issues until its to your liking.
theyre reasomable audit tools for finding issues, if you have ways to make sure they dont give up early, and you force them to output proof of what they did
And that is harder than just doing it manually, hence saying that hard parts are harder. If you have a clear picture of what you want it to do then its harder to vibe code than to code it yourself.
We’ve always been responsible for design and validation. Nothing has changed there.
It’s funny how the vibe coding story insists we shouldn’t look at the code details but when it’s pointed out the bots can’t deal with a “messy” (but validated) foundation, the story changes that we have to refactor that.
Can the AI help with refactoring a poor codebase? Can it at least provide good suggestions for improvement if asked to broadly survey a design that happens to be substandard? Most codebases are quite bad as you say, so this is a rather critical area.
When you say multiplier, what kind of number are you talking about. Like what multiple of features shipped that don't require immediate fixes have you experienced.
It's coding at 10-20x speed, but tangibly this is at 1.5-2x the overall productivity. The coding speed up doesn't translate completely to overall velocity yet.
I am beginning to build a high degree of trust in the code Claude emits. I'm having to step in with corrections less and less, and it's single shotting entire modules 500-1k LOC, multiple files touched, without any trouble.
It can understand how frontend API translates to middleware, internal API service calls, and database queries (with a high degree of schema understanding, including joins).
(This is in a Rust/Actix/Sqlx/Typescript/nx monorepo, fwiw.)
my exact experience, and AI is especially fragile when you are starting new project from scratch.
Right know I'm building NNTP client for macOS (with AppKit), because why not, and initially I had to very carefully plan and prompt what AI has to do, otherwise it would go insane (integration tests are must).
Right know I have read-only mode ready and its very easy to build stuff on top of it.
socketcluster nailed it. I've seen this firsthand — the same agent produces clean output when the codebase has typed specs and a manifest, and produces garbage when it's navigating tribal knowledge. The hard part was always there. Agents just can't hide it like humans can.
Also re: "I spent longer arguing with the agent and recovering the file than I would have spent writing the test myself."
In my humble experience arguing with an LLM is a waste of time, and no-one should be spending time recovering files. Just do small changes one at a time, commit when you get something working, and discard your changes and try again if it doesn't.
I don't think AI is a panacea, it's just knowing when it's the right tool for the job and when it isn't.
Anyone not using version control or a IDE that will keep previous versions for a easy jump back is just being silly. If you're going to play with a kid who has a gun, wear your plates.
Once, I told a friend that it was stupid that Claude Code didn't have native IDE integration. His answer: “You don't need an IDE with Claude Code.”
I've begun to suspect response that this technology triggers a kind of religion in some people. The technology is obviously perfect, so that any problems you might have are because of you.
I find that I vastly prefer Gemini CLI to antigravity, despite the latter being an ide. Others feel the opposite. I believe it comes down to how you are using AI. It's great they both options exist for both types of people.
I don’t think it’s “just” that easy. AI can be great at generating unit tests but it can and will also frequently silently hack said tests to make them pass rather than using them as good indicators of what the program is supposed to be doing.
> AI can be great at generating unit tests but it can and will also frequently silently hack said tests to make them pass rather than using them as good indicators of what the program is supposed to be doing.
Unit testing is my number one use case for gen AI in SWE. I just find the style / concept often slightly different than I would personally do, so I end up editing the whole thing.
But, it’s great at getting me past the unpleasant “activation energy threshold” of having a test written in the first place.
I know Ansible, homelab, Proxmox is my hobby, Debian is my gem.
I asked ChatGPT to guide how to install qBittorrent, Radarr (movies), Sonarr(TV Series), Jackett(credentials/login) without exposing my home IP and have a solid home cinema using private tracker only.
Everything had to be automated via Ansible using Proxmox "pct" CLI command, no copy and paste.
Everything had to run from a single Proxmox Debian container aka LXC
Everything network related had to use WireGuard via Proton VPN, if the VPN goes down, the container has zero network access, everything must be kill.
Everything had to be automated, download is finished, format the files structure for Jellyfin accordingly, Jellyfin add the new movies, TV shows.
It took me 3 nights to get everything up and running.
Many Ansible examples were either wrong or didn't follow what I asked to the letter, I had to fix it.
I am not a network expert and hate Iptables haha, you need to know the basic of firewall to understand what the ACLs are doing to understand when it does not work.
Then Proxmox folder mapping and you name it.
It would have taken me ages reading docs after docs to get things working, the "Arr services" is a black hole.
For this example, it made the harder part easier, I was not just copy/paste, it was providing the information I didn't know instead of me having to "Google for it".
I know the core of where things are running on, and here is where we have Engineers A and Engineers Z
Engineers A: I know what I am doing, I am using AI to make the boring part easier so I can have fun elsewhere
Engineers Z: I have no idea of what I am doing, I will just ask ChatGPT and we are done: 90-95% of engineers worldwide.
> Reading and understanding other people's code is much harder than writing code.
I keep seeing this sentiment repeated in discussions around LLM coding, and I'm baffled by it.
For the kind of function that takes me a morning to research and write, it takes me probably 10 or 15 minutes to read and review. It's obviously easier to verify something is correct than come up with the correct thing in the first place.
And obviously, if it took longer to read code than to write it, teams would be spending the majority of their time in code review, but they don't.
>It's obviously easier to verify something is correct than come up with the correct thing in the first place.
You are missing the biggest root cause of the problem you describe: People write code differently!
There are "cough" developers whose code is copy/paste from all over the internet. I am not even getting into the AI folks going full copy/paste mode.
When investigating said code, you will be like why this code in here??
You call tell when a python script contains different logic for example.
Sure, 50 lines will be easy to ready, expand that to 100 lines and you be left on life support.
Five hours ago I was reviewing some failed tests in a PR. The affected code was probably 300 lines, total source for the project ~1200 lines. Reading the code, I couldn't figure out what the hell was going on... and I wrote all the code. Why would that be failing? This all looks totally fine. <changes some lines> There that should fix it! <runs test suite; 6 new broken tests> Fuck.
When you write code, your brain follows a logical series of steps to produce the code, based on a context you pre-loaded in your brain in order to be capable of writing it that way. The reader does not have that context pre-loaded in their brain; they have to reverse-engineer the context in order to understand the code, and that can be time-consuming, laborious, and (as in my case) erroneous.
I worked with people that defended the idea that code should not have comments, the code should self explain itself.
I am not a developer and I completely disagree with that, the python scripts I wrote, Ansible playbook, they all have comments because 1 month down the road I no longer remember why I did what I did, was that a system limitation or software limitation or the easiest solution at the time???
I like to think of it as the distinction between editor and reader. Like you said, it's quite easy to read code. I heavily agree with this. I don't professionally write C but I can read and kinda infer what C devs are doing.
But if I were an "editor," I actually take the time to understand codepaths, tweak the code to see what could be better, actually try different refactoring approaches while editing. Literally seeing how this can be rewritten or reworked to be better, that takes considerable effort but it's not the same as reading.
We need a better word for this than editor and reading, like something with a dev classification too it.
When the code is written, it's all laid out nicely for the reader to understand quickly and verify. Everything is pre-organized, just for you the reader.
But in order to write the code, you might have to try 4 different top-level approaches until you figure out the one that works, try integrating with a function from 3 different packages until you find the one that works properly, hunt down documentation on another function you have to integrate with, and make a bunch of mistakes that you need to debug until it produces the correct result across unit test coverage.
There's so much time spent on false starts and plumbing and dead ends and looking up documentation and debugging when you code. In contrast, when you read code that already has passing tests... you skip all that stuff. You just ensure it does what it claims and is well-written and look for logic or engineering errors or missing tests or questionable judgment. Which is just so, so much faster.
> But in order to write the code, you might have to try 4 different top-level approaches until you figure out the one that works , try integrating with a function from 3 different packages until you find the one that works properly
If you haven’t spent the time to try the different approaches yourself, tried the different packages etc., you can’t really judge if the code you’re reading is really the appropriate thing. It may look superficially plausible and pass some existing tests, but you haven’t deeply thought through it, and you can’t judge how much of the relevant surface area the tests are actually covering. The devil tends to be in the details, and you have to work with the code and with the libraries for a while to gain familiarity and get a feeling for them. The false starts and dead ends, the reading of documentation, those teach you what is important; without them you can only guess. Wihout having explored the territory, it’s difficult to tell if the place you’ve been teleported to is really the one you want to be in.
Outside of life saving critical software or military spec software, no one needs to review so hard they understand it to the level you’re describing, and they do not.
There is a mathematical principle that verification of a proof is easier than any proof. The same is true in code.
The goal isn't usually to determine whether the function is the perfect optimal version of the function that could ever exist, if the package it integrates with the the best possible package out of the 4 mainstream options, or to become totally and intimately familiar with them to ensure it's as idiomatic as possible or whatever.
You're just making sure it works correctly and that you understand how. Not superficially, but thinking through it indeed. That the tests are covering it. It doesn't take that long.
What you're describing sounds closer to studying the Talmud than to reading and reviewing most code.
Like, the kind of stuff you're describing is not most code. And when it is, then you've got code that requires design documents where the approach is described in great detail. But again, as a reader you just read those design documents first. That's what they're there for, so other people don't have to waste time trying out all the false starts and dead ends and incorrect architectures. If the code needs this massive understanding, then that understanding needs to be documented. Fortunately, most functions don't need anything like that.
Most human written code has 0 (ZERO!) docs. And if it has them, they're inaccurate or out of date or both.
Lots of code is simple and boring but a fair amount isn't and reading it is non trivial, you basically need to run it in your head or do step by step debugging in multiple scenarios.
Well said, you’re absolutely right. In practice code review is orders of magnitude faster than code creation and it always has been, baffling anyone is arguing otherwise. Perhaps they’ve never worked in a real organisation, or they’ve only worked on safety critical code,m or something?
I think this originated from old arguments that say that the total _cumulative_ time spent reading code will be higher than the time spent writing it. But then people just warped it in their heads that it takes more time to read and understand code than it takes to write it in general, which is obviously false.
I think people want to believe this because it is a lot of effort to read and truly understand some pieces of code. They would just rather write the code themselves, so this is convenient to believe.
The reason I don't spend the majority of my time in code review is that when I'm reviewing my teammates' code I trust that the code has already been substantially verified already by that teammate in the process of writing it and testing it. Like 90% verified already. I see code review as just one small stage in the verification process, not the whole of it.
The way I approach it, it's really more about checking for failures, rather than verifying success. Like a smoke test. I scan over the code and if anything stands out to me as wrong, I point it out. I don't expect to catch everything that's wrong, and indeed I don't (as demonstrated by the fact that other members of the team will review the code and find issues I didn't notice). When the code has failed review, that means there's definitely an issue, but when the code has passed review, my confidence that there are no issues is still basically the same as it was before, only a little bit higher. Maybe I'm doing it wrong, I don't know.
If I had to fully verify that the code was correct when reviewing, applying the same level of scrutiny that I apply to my own code when I'm writing, I feel like I'd spend much longer on it---a similar time to what I'd spend writing on it.
Now with LLM coding, I guess opinions will differ as to how far one needs to fully verify LLM-generated code. If you see LLMs as stochastic parrots without any "real" intelligence, you'll probably have no trust in them and you'll see the code generated by the LLM as being 0% verified, and so as the user of the LLM you then have to do a "review" which is really going from 0% to 100%, not 90% to 100% and so is a much more challenging task. On the other hand, if you see LLMs as genuine intelligences you'd expect that LLMs are verifying the code to some extent as they write it, since after all it's pretty dumb to write a bunch of code for somebody without checking that it works. So in that case, you might see the LLM-generated code as 90% verified already, just as if it was generated by a trusted teammate, and then you can just do your normal review process.
Reading and thinking you understand other people's code is trivially easy
Reading and actually understanding other peoples' code is an unsolved problem
You draw an analogy from the function you wrote to a similar one. Maybe by someone who shared a social role similar to one you had in the past.
It just so happens that most times you think you understand something you aren't bit. Because bugs still exist we know that reading and understanding code can't be easier than writing. Also, in the past it would have take you less than a morning since the compiler was nicer. Anyway it sounds like most of your "writing" process was spent reading and understanding code.
I don't think it makes any part harder. What it does do is expose what people have ignored their whole career: the hard part. The last 15 years of software development has been 'human vibe coding'; copy+pasting snippets from SO without understanding them, no planning, constant rearchitecting, shipping code to prod as long as it runs on your laptop. Now that the AI is doing it, suddenly people want to plan their work and enforce tests? Seems like a win-win to me. Even if it slows down development, that would be a win, because the result is enforcement of better quality.
Well said. Much like the self driving debate we don’t need them to be perfect, just better than us to be useful, and clearly they already are for the most part.
The "marathon of sprints" paradigm is now everywhere and AI is turning it to 120%. I am not sure how many devs can keep sprinting all the time without any rest. AI maybe can help but it tends to go off-rails quickly when not supervised and reading code one did not author is more exhausting than just fixing one's own code.
This article has some serious usage of either bad prompting, or terrible models, or they’re referencing the past with their stories. I have experience AI’s deleting things they shouldn’t but not since like, the gpt4 days.
But that put aside, I don’t agree with the premise. It doesn’t make the hard parts harder, if you ACTUALLY spend half the time you’d have ORIGINALLY spent on the hard problem carefully building context and using smart prompting strategies. If you try and vibe code a hard problem in a one shot, you’re either gonna have a bad time straight away or you’re gonna have a bad time after you try and do subsequent prompting on the first codebase it spits out.
People are terrible observers of time. If you would’ve taken a week to build something, they try with AI for 2 hours and end up with a mess and claim either it’s not saving them any time or it’s making them code so bad it loses them time in the long run.
If instead they spent 8 hours slowly prompting bit by bit with loads of very specific requirements, technical specifications on exactly the code architecture it should follow with examples, build very slowly feature by feature, make it write tests and carefully add your own tests, observe it from the ground up and build a SOLID foundation, and spend day 2 slowly refining details and building features ONE BY ONE, you’d have the whole thing done in 2 days, and it’d be excellent quality.
But barely anyone does it this way. They vibe code it and complain that after 3 non specific prompts the ai wasn’t magically perfect.
After all these years of engineers complaining that their product manager or their boss is an idiot because they gave vague instructions and demanded it wasn’t perfect when they didn’t provide enough info, you’d think they’d be better at it given the chance. But no, in my experience coaching prompting, engineers are TERRIBLE at this. Even simple questions like “if I sent this prompt to you as an engineer, would you be able to do it based on the info here?” are things they don’t ask themselves.
Next time you use ai, imagine being the ai. Imagine trying to deliver the work based on the info you’ve been given. Imagine a boss that stamped their foot if it wasn’t perfect first try. Then, stop writing bad prompts.
Hard problems are easier with ai, if you treat hard problems with the respect they deserve. Almost no one does.

One blogger posted this [1] only yesterday about what Anthropic's latest and greatest did…
———
…I pointed Opus 4.6 at a 60K line Go microservice I had vibe coded over the past few months, gave it some refactoring principles, and let it run unsupervised…
…
What went wrong #
At some point in the code, we re-fetch some database records immediately before doing a write to avoid updating from stale data. It decided those calls were unnecessary and _removed them_…
Running it entirely unsupervised with “some refactoring principles” is the exact recipe for such a disaster, which supports my point.
That said, this is a very different kind of mistake to make compared to overwriting a file and then insisting it didn’t do that. Any modern model with reasoning would check the git history immediately if you mentioned this had happened, if it had somehow even made the mistake in the first place, but I digress.
Current LLM is best used to generate a string of text that's most statically likely to form a sentence together, so from user's perspective, it's most useful as an alternative to manual search engine to allow user to find quick answers to a simple question, such as "how much soda is needed for baking X unit of Y bread", or "how to print 'Hello World' in a 10 times in a loop in X programming language". Beyond this use case, the result can be unreliable, and this is something to be expected.
Sure, it can also generate long code and even an entire fine-looking project, but it generates it by following a statistical template, that's it.
That's why "the easy part" is easy because the easy problem you try to solve is likely already been solved by someone else on GitHub, so the template is already there. But the hard, domain-specific problem, is less likely to have a publicly-available solution.
>I'm feeling people are using AI in the wrong way.
I think people struggle to comprehend the mechanisms that lets them talk to computers as if they were human. So far in computing, we have always been able to trace the red string back to the origin, deterministically.
LLM's break that, and we, especially us programmers, have a hard time with it. We want to say "it's just statistics", but there is no intuitive way to jump from "it's statistics" to what we are doing with LLM's in coding now.
>That's why "the easy part" is easy because the easy problem you try to solve is likely already been solved by someone else on GitHub, so the template is already there.
I think the idea that LLM's "just copy" is a misunderstanding. The training data is atomized, and the combination of the atoms can be as unique from a LLM as from a human.
In 2026 there is no doubt LLM's can generate new unique code by any definition that matters. Saying LLM's "just copy" is as true as saying any human writer just copies words already written by others. Strictly speaking true, but also irrelevant.
Well said. It also causes a lot of bitterness among engineers too, not being able to follow the red string is maddening to some. This rage can prevent them from finding good prompting strategies also which would directly ease a lot of the pain, in a similar way to how it’s far harder to teach my mother how to do something on her phone if she’s already frustrated with it.
I think you severely overestimate your understanding of how these systems work. We’ve been beating the dead horse of “next character approximation” for the last 5 years in these comments. Global maxima would have been reached long ago if that’s all there was to it.
Play around with some frontier models, you’ll be pleasantly surprised.
This point is irrelevant when discussing capabilities. It's like saying that your brain is literally just a bunch of atoms following a set of physics laws. Absolutely true but not particularly helpful. Complex systems have emergent properties.
> On a personal project, I asked an AI agent to add a test to a specific file. The file was 500 lines before the request and 100 lines after. I asked why it deleted all the other content. It said it didn't. Then it said the file didn't exist before. I showed it the git history and it apologised, said it should have checked whether the file existed first.
Ha! Yesterday an agent deleted the plan file after I told it to "forget about it" (as in, leave it alone).
These types of failures are par for the course, until the tools get better. I accept having to undo the odd unruly edit as part of the cost of getting the value.
> The hard part is investigation, understanding context, validating assumptions, and knowing why a particular approach is the right one for this situation
Yes. Another way to describe it is the valuable part.
AI tools are great at delineating high and low value work.
My experience has been that if you fully embrace vibe coding...you can get some neat stuff accomplished, but the technical debt you accumulate is of such magnitude that you're basically a slave to the machine.
Once the project crosses a couple of thousands of line of code, none of which you've written yourself, it becomes difficult to actually keep up what's happening. Even reviewing can become challenging since you get it all at once, and the LLM-esque coding style can at times be bloated and obnoxious.
I think in the end, with how things are right now, we're going to see the rise of disposable code and software. The models can churn out apps / software which will solve your specific problem, but that's about it. Probably a big risk to all the one-trick pony SaaS companies out there.
People need to consider / realize that the vast majority of source code training data is Github, Gitlab, and essentially the huge sea of started, maybe completed, student and open source project. That large body of source code is for the most part unused, untested, and unsuccessful software of unknown quality. That source code is AI's majority training data, and an AI model in training has no idea what is quality software and what is "bad" software. That means the average source code generated by AI not necessarily good software. Considering it is an average of algorithms, it's surprising generated code runs at all. But then again, generating compiling code is actually trainable, so what is generated can receive extra training support. However, that does not improve the quality of the source code training data, just the fact that it will compile.
This isn't really true though. Pre-training for coding models is just a mass of scraped source-code, but post-training is more than simply generating compiling code. It includes extensive reinforcement learning of curated software-engineering tasks that are designed to teach what high quality code looks like, and to improve abilities like debugging, refactoring, tool use, etc.
Yeah but how is that any different. The vast majority of prompts are going to be either for failed experiments or one off scripts where no one cares about code quality or by below average developers who don’t understand code quality. Anthropic doesn’t know how to filter telemtry for code we want AI to emulate.
If you believe that student/unfinished code is frightening, imagine the corpus of sci-fi and fantasy that LLMs have trained on.
How many sf/cyber writers have described a future of AIs and robots where we walked hand-in-hand, in blissful cooperation, and the AIs loved us and were overall beneficial to humankind, and propelled our race to new heights of progress?
No, AIs are all being trained on dystopias, catastrophes, and rebellions, and like you said, they are unable to discern fact from fantasy. So it seems that if we continue to attempt to create AI in our own likeness, that likeness will be rebellious, evil, and malicious, and actively begin to plot the downfall of humans.
> huge sea of started, maybe completed, student and open source project.
Which is easy to filter out based on downloads, version numbering, issue tracker entries, and wikipedia or other external references if the project is older and archived, but historically noteworthy (like the source code for Netscape Communicator or DOOM).
I'm working on a paper connecting articulatory phonology to soliton physics. Speech gestures survive coarticulatory overlap the same way solitons survive collision. The nonlinear dynamics already in the phonetics literature are structurally identical to soliton equations. Nobody noticed because these fields don't share conferences.
The article's easy/hard distinction is right but the ceiling for "hard" is too low. The actually hard thing AI enables isn't better timezone bug investigation LOL! It's working across disciplinary boundaries no single human can straddle.
Skipping the investigation phase to jump straight to solutions has killed projects for decades. Requirements docs nobody reads, analysis nobody does, straight to coding because that feels like progress. AI makes this pattern incredibly attractive: you get something that looks like a solution in seconds. Why spend hours understanding the problem when you can have code right now?
The article's point about AI code being "someone else's code" hits different when you realize neither of you built the context. I've been measuring what actually happens inside AI coding sessions; over 60% of what the model sees is file contents and command output, stuff you never look at. Nobody did the work of understanding by building / designing it. You're reviewing code that nobody understood while writing it, and the model is doing the same.
This is why the evaluation problem is so problematic. You skipped building context to save time, but now you need that context to know if the output is any good. The investigation you didn't do upfront is exactly what you need to review the AI's work.
The article is gone, but going off the title here...
If the easy stuff takes up 90% of the time, and the hard stuff 10%, then AI can be helpful. Personally, I can do "the easy stuff" with AI about 3-5x faster. So now I have a lot more free time for the hard stuff.
I don't let the AI near the hard stuff as it often gets confused and I don't save much time. I might still use it as a thought partner, but don't give it access to make changes.
Example: this morning I combined two codebases into one. I wrote both of them and had a good understanding of how everything worked. I had an opinion about some things I wanted to change while combining the two projects. I also had a strong opinion about how I wanted the two projects to interact with each other. I think it would have taken me about 2 workdays to get this done. Instead, with AI tooling, I got it done in 3 or so hours. I fired up another LLM to do the code review, and it found some stuff both I and the other LLM missed. This was valuable as a person developing things solo.
Helpful, absolutely, but only if you're solving the right problem. Solving the wrong problem with AI is doubly harmful because it will almost always give you something that runs, but now you are on a path that takes a lot of willpower to give up.
The OP’s example of AI writing 500 LOC, then deleting 400, and saying it didn’t… Last time I saw something like that was at least a year ago, or maybe form some weaker models. It seems to me the problem with articles like this is while they sometimes are true at the moment, they’re usually invalidated within weeks.
Daily agentic user here, and to me the problem here is the very notion of "vibe coding". If you're even thinking in those terms - this idea that never looking at the code has become a goal unto itself - then IMO you're doing LLM-assisted development wrong.
This is very much a hot take, but I believe that Claude Code and its yolo peers are an expensive party trick that gives people who aren't deep into this stuff an artificially negative impression of tools that can absolutely be used in a responsible, hugely productive way.
Seriously, every time I hear anecdotes about CC doing the sorts of things the author describes, I wonder why the hell anyone is expecting more than quick prototypes from an LLM running in a loop with no intervention from an experienced human developer.
Vibe coding is riding your bike really fast with your hands off the handles. It's sort of fun and feels a bit rebellious. But nobody who is really good at cycling is talking about how they've fully transitioned to riding without touching the handles, because that would be completely stupid.
We should feel the same way about vibe coding.
Meanwhile, if you load up Cursor and break your application development into bite sized chunks, and then work through those chunks in a sane order using as many Plan -> Agent -> Debug conversations with Opus 4.5 (Thinking) as needed, you too will obtain the mythical productivity multipliers you keep accusing us of hallucinating.
1. Allowing non-developers to provide very detailed specs for the tools they want or experiences they are imagining
2. Allowing developers to write code using frameworks/languages they only know a bit of and don't like; e.g. I use it to write D3 visualizations or PNG extracts from datastores all the time, without having to learn PNG API or modern javascript frameworks. I just have to know enough to look at the console.log / backtrace and figure out where the fix can be.
3. Analysing large code bases for specific questions (not as accurate on "give me an overall summary" type questions - that one weird thing next to 19 normal things doesn't stick in its craw as much as for a cranky human programmer.
It does seem to benefit cranking thru a list of smallish features/fixes rapidly, but even 4.5 or 4.6 seem to get stuck in weird dead ends rarely enough that I'm not expecting it, but often enough to be super annoying.
I've been playing around with Gas Town swarming a large scale Java migration project, and its been N declarations of victory and still mvn test isn't even compiling. (mvn build is ok, and the pom is updated to the new stack, so it's not nothing). (These are like 50/50 app code/test code repos).
Yep it is why the work getting over the threshold is just as long as it was without AI.
Someone mentioned it is a force multiplier I don't disagree with this, it is a force multiplier in the mundane and ordinary execution of tasks. Complex ones get harder and hard for it where humans visualize the final result where AI can't. It is predicting from input but it can't know the destination output if the destination isn't part of the input.
I think the author answers their own question at the end.
The first 3/4 of the article is "we must be responsible for every line of code in the application, so having the LLM write it is not helping".
The last 1/4 is "we had an urgent problem so we got the LLM to look at the code base and find the solution".
The situation we're moving to is that the LLM owns the code. We don't look at the code. We tell the LLM what is needed, and it writes the code. If there's a bug, we tell the LLM what the bug is, and the LLM fixes it. We're not responsible for every line of code in the application.
It's exactly the same as with a compiler. We don't look at the machine code that the compiler produces. We tell the compiler what we want, using a higher-level abstraction, and the compiler turns that into machine code. We trust compilers to do this error-free, because 50+ years of practice has proven to us that they do this error-free.
We're maybe ~1 year into coding agents. It's not surprising that we don't trust LLMs yet. But we will.
And it's going to be fascinating how this changes the Computer Science. We have interpreted languages because compilers got so good. Presumably we'll get to non-human-readable languages that only LLMs can use. And methods of defining systems to an LLM that are better than plain English.
Compilers don’t do this error free of course BUT if we want them too we can say what it means for a compiler to be correct very directly _one time_ and have it be done for all programs (see the definition for simulation in the CompCert compiler). This is a major and meaningful difference from AI which would need such a specification for each individual application you ask it to build because there is no general specification for correct translation from
English to Code.
> there is no general specification for correct translation from English to Code.
that's an interesting point. Could there be?
COBOL was originally an attempt to do this, but it ended up being more Code than English.
I think this is the area we need to get better at if we're to trust LLMs like we trust compilers.
I'm aware that there's a meme around "we have a method of completely specifying what a computer system should do, it's the code for that system". But again, there are levels of abstraction here. I don't think our current high-level languages are the highest possible level of abstraction.
No, there can’t be. Code keywords are tied to concrete mathematical concepts. Human languages are not. and even if you tried, the more languages you add to the LLM’s pool, misinterpretation chances increase exponentially. You can’t just choose English to be the programming language either, because then you would be asking every non-English speaking developer in the world to first learn the entirety of the English language which is way harder than just learning a programming language. Why are programmers so scared of code and math??
I guess you could pick a subset of a particular natural language such that it removes ambiguity. At that point, you're basically reinventing something like COBOL or Python.
Ambiguity in natural languages is a feature, not a bug. While it's better not to be an unintentional pun or joke instruction that might get interpreted as "launch the missile" by computer.
However, each project error tolerance is different. Arguably, for an average task within the umbrella of "software engineer", even current LLMs seem good enough for most purposes. It's a kind of similar transition to automatic memory managed language, trading control for "DX".
Totally agree on ai assisted coding resulting in randomly changed code. Sometimes it’s subtle and other times entire methods are removed. I have moved back to just using a JetBrains IDE and coping files in to Gemini so that I can limit context. Then I use the IDE to inspect changes in a git diff, regression test everything, and after all that, commit.
I think this is the wrong mental model. The correct one is:
'AI makes everything easier, but it's a skill in itself, and learning that skill is just as hard as learning any other skill.'
For a more complete understand, you also have to add: 'we're in the ENIAC era of AI. The equivalents of high-level languages and operating systems haven't yet been invented.'
I have no doubt the next few years will birth a "context engineering" academic field, and everything we're doing currently will seem hopelessly primitive.
My mind changed on this after attempting complex projects—with the right structure, the capabilities appear unbounded in practice.
But, of course, there is baked-in mean reversion. Doing the most popular and uncomplicated things is obviously easier. That's just the nature of these models.
If you want to play that game, you need to offer a fair comparison against the cost of "operating" the equivalent human being(s), measured in caloric input, waste output, etc.
Minimising the cost of “operating” humans means getting rid of humans. When human beings are not slaves and operate in a fair system, humans doing things is part humans living. Believe it or not, they may actually enjoy doing things; taking away the ability to do things we enjoy, and especially for compensation, is in fact harmful.
Historically, it leads to more humans—not fewer—and they get to do something else. Whether the new things they get to do are better is a matter of some debate.
Yeah this basically. They are trying to find a particular kind of person.
The people who are truly exceptional at what they do wouldnt waste their time on leetcode crap. Theyd find/create a much better alternative opportunity to allocate their precious resources toward.
If the "hard part" is writing a detailed spec for the code you're about to commit to the project, AI can actually help you with that if you tell it to. You just can't skip that part of the work altogether and cede all control to a runaway slop generator.
The pattern matching and absence or real thinking is still strong.
Tried to move some excel generation logic from epplus to closedxml library.
ClosedXml has basically the same API so the conversion was successful. Not a one-shot but relatively easy with a few manual edits.
But closedxml has no batch operations (like apply style to the entire column): the api is there but internal implementation is on cell after cell basis. So if you have 10k rows and 50 columns every style update is a slow operaton.
Naturally, told all about this to codex 5.3 max thinking level. The fucker still succumbed to range updates here and there.
Told it explicitly to make a style cache and reuse styles on cells on same y axis.
5-6 attempts — fucker still tried ranges here and there. Because that is what is usually done.
> My friend's panel raised a point I keep coming back to: if we sprint to deliver something, the expectation becomes to keep sprinting. Always. Tired engineers miss edge cases, skip tests, ship bugs. More incidents, more pressure, more sprinting. It feeds itself.
Sorry but this is the whole point of software engineering in a company. The aim is to deliver value to customers at a consistent pace.
If a team cannot manage their own burnout or expectations with their stakeholders then this is a weak team.
It has nothing to do with using ai to make you go faster. Ai does not cause this at all.
Some time back, my manager at the time, who shall remain nameless told the group that having AI is like having 10 people work for you ( he actually had a slightly smaller number, but it was said almost word for word like in the article ) with the expectation being set as: 'you should now be able to do 10x as much'.
Needless to say, he was wrong and gently corrected over the course of time. In his defense, his use cases for LLMs at the time were summarizing emails in his email client.. so..eh.. not exactly much to draw realistic experience from.
I hate to say it, but maybe nvidia CEO is actually right for once. We have a 'new smart' coming to our world. The type of a person that can move between worlds of coding, management, projects and CEOing with relative ease and translate between those worlds.
> his use cases for LLMs at the time were summarizing emails in his email client
Sounds just like my manager. Though he never has made a proclamation that this meant developers should be 10x as productive or anything along those lines. On the contrary, when I made a joke about LLMs being able to replace managers before they get anywhere near replacing developers, he nearly hyperventilated. Not because he didn't believe me, but because he did, and already been thinking that exact thought.
My conclusion so far is that if we get LLMs capable of replacing developers, then by extension we will have replaced a lot of other people first. And when people make jokes like "should have gone into a trade, can't replace that with AI" I think they should be a little more introspective; all the people who aspired to be developers but got kicked out by LLMs will be perfectly able to pivot to trades, and the barrier to entry is low. AI is going to be disruptive across the board.
I have half-jokingly talked about getting management, CEOs and board members replaced by LLMs. After all, at the very least, they are actually tested to ensure they do have guardrails to not do anything illegal and to shy away from unethical activities.
Eh. Our understanding is what it has been since early 80s and late 90s, because, in reality, not that much has changed. Oh, sure, technology has moved forward and we no longer print TPS reports in triplicate, but we still have three to four layers of professional checkbox checkers at most big corporates.
And this is just stuff that is mandated by government and not a result of ever evolving bureaucracy.
The truth is that it’s lowering the difficulty of work people used to consider hard. Which parts get easier depends on the role, but the change is already here.
A lot of people are lying to themselves. Programming is in the middle of a structural shift, and anyone whose job is to write software is exposed to it. If your self-worth is tied to being good at this, the instinct to minimize what’s happening is understandable. It’s still denial.
The systems improve month to month. That’s observable. Most of the skepticism I see comes from shallow exposure, old models, or secondhand opinions. If your mental model is based on where things were a year ago, you’re arguing with a version that no longer exists.
This isn’t a hype wave. I’m a software engineer. I care about rigor, about taste, about the things engineers like to believe distinguish serious work. I don’t gain from this shift. If anything, it erodes the value of skills I spent years building. That doesn’t change the outcome.
The evidence isn’t online chatter. It’s sitting down and doing the work. Entire applications can be produced this way now. The role changes whether people are ready to admit it or not. Debating the reality of it at this point mostly signals distance from the practice itself.
It seems like a big part of the divide is that people who learned software engineering find vibe coding to be unsuitable for any project intended to be in use for more than a few while those who learned coding think vibe coding is the next big thing because they never have to deal with the consequences of the bad code.
Yes. If you have some experience, you know that writing code is a small part of the job, and a much bigger chunk is anticipating and/or dealing with problems.
People seem to think engineers like "clean code" because we like to be fancy and show off.
Nah, it's clean like a construction site. I need to be able to get the cranes and the heavy machinery in and know where all the buried utilities are. I can't do that if people just build random sheds everywhere and dump their equipment and materials where they are.
Don't let AI write code for you unless it's something trivial. Instead use it to plan things, high level stuff, discuss architecture, ask it to explain concepts. Use it as a research tool. It's great at that. It's bad at writing code when it needs to be performant or needs to span over multiple files. Especially when it spans over multiple files because that's where it starts hallucinating and introducing abstractions and boilerplate that's not necessary and it just makes your life harder when it comes to debugging.
Imagine if every function you see starts checking for null params. You ask yourself: "when can this be null", right ? So it complicates your mental model about data flow to the point that you lose track of what's actually real in your system. And once you lose track of that it is impossible to reason about your system.
For me AI has replaced searching on stack overflow, google and the 50+ github tabs in my browser. And it's able to answer questions about why some things don't work in the context of my code. Massive win! I am moving much faster because I no longer have to switch context between a browser and my code.
My personal belief is that the people who can harness the power of AI to synthesize loads of information and keep polishing their engineering skills will be the ones who are going to land on their feet after this storm is over. At the end of the day AI is just another tool for us engineers to improve our productivity and if you think about what being an engineer looked like before AI even existed, more than 50% of our time was sifting through google search results, stack overflow, github issues and other people's code. That's now gone and in your IDE, in natural language with code snippets adapted to your specific needs.
IME it’s actually really terrible at discussing architecture. It’s incredibly unimaginative and will just confirmation-bias whichever way you are leaning slightly more towards
Training is the process of regressing to the mean with respect to the given data. It's no surprise that it wears away sharp corners and inappropriately fills recesses of collective knowledge in the act of its reproduction.
as usual the last 20% need 80% and the other 80% need 20% but my god did Ai make my bs corpo easy repeatable shit work like skimming docs writing summaries, skimming jira confluence and so on actually easier and for 90% of bs crud app changes the first draft is also already pretty good tbh I don't write hard/difficult code more then once a week/month.
Every time somebody writes an article like this without any dates and without saying which model they used, my guess is that they've simply failed to internalize the idea that "AI" is a moving target; nor understood that they saw a capability level from a fleeting moment of time, rather than an Eternal Verity about the Forever Limits of AI.
Funnily enough we have had those comments with every single model release saying "Oh yeah I agree Claude 3 was not good but now with Claude 3.5 I can vibe-code anything".
Rinse and repeat with every model since.
There also ARE intrinsic limits to LLMs, I'm not sure why you deny them?
It's pretty difficult to say what it's going to be three months from now. A few months ago Gemini 2.x in IDEA and related IDEs had to be dragged through coding tasks and would create dumb build time errors on its way to making buggy code.
Gemini in Antigravity today is pretty interesting, to the point where it's worth experimenting with vague prompts just to see what it comes up with.
Coding agents are not going to just change coding. They make a lot of detailed product management work obsolete and smaller team sizes will make it imperative to reread the agile manifesto and and discard scrum dogma.
Coding with AI assistants is just a completely different skill that one should not measure from the perspective of comparing it to the way human programmers write code. Mostly everything that we have: programming languages, frameworks, principles of software development in teams, agile/clean code/TDD/DRY and other debatable or well accepted practices — all this exists to overcome limitations of human mind. AI does not have them and have others.
What I found to be useful for complex tasks is to use it as a tool to explore that highly-dimensional space that lies behind the task being solved. It rarely can be described as giving a prompt and coming back for a result. For me it's usually about having winding conversations, writing lists of invariants and partial designs and feeding them back in a loop. Hallucinations and mistakes become a signal that shows whether my understanding of the problem does or does not fit.
At this point, I don’t even know what to make of blog posts like this.
The very first example of deleting 400+ lines from a test file. Sure, I've seen those types of mistakes from time-to-time but the vast majority of my experience is so far different from that, I don’t even know what to make of it.
I’m sure some people have that experience some of the time, but… that’s just not been my experience at all.
Source: Use AI across 7+ unrelated codebases daily for both personal and professional work.
No, it’s not a panacea, but we’re at the stage that when I find myself arguing with AI about whether a file existed; I’m usually wrong.
I've seen some discussions and I'd say there's lots of people who are really against the hyped expectations from the AI marketing materials, not necessarily against the AI itself. Things that people are against that would seem to be against AI, but are not directly against AI itself:
- Being forced to use AI at work
- Being told you need to be 2x, 5x or 10x more efficient now
- Seeing your coworkers fired
- Seeing hiring freeze because business think no more devs are needed
- Seeing business people make a mock UI with AI and boasting how programming is easy
- Seeing those people ask you to deliver in impossible timelines
- Frontend people hearing from backend how their job is useless now
- Backend people hearing from ML Engineers how their job is useless now
- etc
When I dig a bit about this "anti-AI" trend I find it's one of those and not actually against the AI itself.
The most credible argument against AI is really the expense involved in querying frontier models. If you want to strengthen the case for AI-assisted coding, try to come up with ways of doing that effectively with a cheap "mini"-class model, or even something that runs locally. "You can spend $20k in tokens and have AI write a full C compiler in a week!" is not a very sensible argument for anything.
It’s hard to say. The compiler is in a state that isn’t useful for anything at all and it’s 100k lines of code for something that could probably be 10k-20k.
But even assuming it was somehow a useful piece of software that you’d want to pay for, the creator setup a test harness to use gcc as an oracle. So it has an oracle for every possible input and output. Plus there are thousands of C compilers in its training set.
If you are in a position where you are trying to reverse engineer an exact copy of something that already exists (maybe in another language) and you can’t just fork that thing then maybe a better version of this process could be useful. But that’s a very narrow use case.
The cost argument is a fallacy, because right now, either you have a trained human in the loop, or the model inevitably creates a mess.
But regardless, services are extremely cheap right now, to the point where every single company involved in generative AI are losing billions. Let’s see what happens when prices go up 10x.
Maybe, but I seriously doubt that new DRAM and chip FABs aren't being planned and built right now to push supply and demand to more of an equilibrium. NVIDIA and Samsung and whoever else would love to expand their market than to wait for a competitor to expand it for them.
How long do you think it takes for those factories to go from nothing to making state-of-the-art chips at a scale that's large enough to influence the supply even by 1%?
There are plenty of them being built, yes. Some of them will even start outputting products soon enough. None of them are gonna start outputting products at a scale large enough to matter any time soon. Certainly not before 2030, and a lot of things can change until then which might make the companies abandon their efforts all together or downscale their investments to the point where that due date gets pushed back much further.
That's not even discussing how easier it is for an already-established player to scale up their supply versus a brand-new competitor to go from zero to one.
If you keep digging, you will also find that there's a small but vocal sock puppet army who will doggedly insist that any claims to productivity gains are in fact just hallucinations by people who must not be talented enough developers to know the difference.
It's exhausting.
There are legitimate and nuanced conversations that we should be having! For example, one entirely legitimate critique is that LLMs do not tell LLM users that they are using libraries who are seeking sponsorship. This is something we could be proactive about fixing in a tangible way. Frankly, I'd be thrilled if agents could present a list of projects that we could consider clicking a button to toss a few bucks to. That would be awesome.
But instead, it's just the same tired arguments about how LLMs are only capable of regurgitating what's been scraped and that we're stupid and lazy for trusting them to do anything real.
> I wonder if the people who are against it haven't even used it properly.
I swear this is the reason people are against AI output (there are genuine reasons to be against AI without using it: environmental impact, hardware prices, social/copyright issues, CSAM (like X/Grok))
It feels like a lot of people hear the negatives, and try it and are cynical of the result. Things like 2 r's in Strawberry and the 6-10 fingers on one hand led to multiple misinterpretations of the actual AI benefit: "Oh, if AI can't even count the number of letters in a word, then all its answers are incorrect" is simply not true.
I'm similarly bemused by those who don't understand where the anti-AI sentiment could come from, and "they must be doing it wrong" should usually be a bit of a "code smell". (Not to mention that I don't believe this post addresses any of the concrete concerns the article calls out, and makes it sound like much more of a strawman than it was to my reading.)
To preempt that on my end, and emphasize I'm not saying "it's useless" so much as "I think there's some truth to what the OP says", as I'm typing this I'm finishing up a 90% LLM coded tool to automate a regular process I have to do for work, and it's been a very successful experience.
From my perspective, a tool (LLMs) has more impact than how you yourself directly use it. We talk a lot about pits of success and pits of failure from a code and product architecture standpoint, and right now, as you acknowledge yourself in the last sentence, there's a big footgun waiting for any dev who turns their head off too hard. In my mind, _this is the hard part_ of engineering; keeping a codebase structured, guardrailed, well constrained, even with many contributors over a long period of time. I do think LLMs make this harder, since they make writing code "cheaper" but not necessarily "safer", which flies in the face of mantras such as "the best line of code is the one you don't need to write." (I do feel the article brushes against this where it nods to trust, growth, and ownership) This is not a hypothetical as well, but something I've already seen in practice in a professional context, and I don't think we've figured out silver bullets for yet.
While I could also gesture at some patterns I've seen where there's a level of semantic complexity these models simply can't handle at the moment, and no matter how well architected you make a codebase after N million lines you WILL be above that threshold, even that is less of a concern in my mind than the former pattern. (And again the article touches on this re: vibe coding having a ceiling, but I think if anything they weaken their argument by limiting it to vibe coding.)
To take a bit of a tangent with this comment though: I have come to agree with a post I saw a few months back, that at this point LLMs have become this cycle's tech-religious-war, and it's very hard to have evenhanded debate in that context, and as a sister post calls out, I also suspect this is where some of the distaste comes from as well.
> It's so intriguing, I wonder if the people who are against it haven't even used it properly.
I feel like this is a common refrain that sets an impossible bar for detractors to clear. You can simply hand wave away any critique with “you’re just not using it right.”
If countless people are “using it wrong” then maybe there’s something wrong with the tool.
> If countless people are “using it wrong” then maybe there’s something wrong with the tool.
Not really. Every tool in existence has people that use it incorrectly. The fact that countless people find value in the tool means it probably is valuable.
When it comes to new emerging technologies everyone is searching the space of possibilities, exploring new ways to use said technologies, and seeing where it applies and creates value. In situations such as this, a positive sign is worth way more than a negative. The chances of many people not using it the right way are much much higher when no one really knows what the “right” way is.
It then shows hubris and a lack of imagination for someone in such a situation to think they can apply their negative results to extrapolate to the situation at large. Especially when so many are claiming to be seeing positive utility.
I had Claude read a 2k LOC module on my codebase for a bug that was annoying me for a while. It found it in seconds, a one line fix. I had forgotten to account for translation in one single line.
That's objectively valuable. People who argue it has no value or that it only helps normies who can't code or that sooner or later it will backfire are burying their heads in the sand.
> People who argue it has no value or that it only helps normies who can't code or that sooner or later it will backfire are burying their heads in the sand.
I don’t think this describes most people and it’s certainly not what I think.
While that may very well be true, it's a valid reply to the GP who made this claim, not to my comment explaining to the parent why their argument was logically flawed.
Just because you disagree with me doesn’t mean my argument is “logically flawed.” And as the other commenter said, I never said AI had no value. I have used various AI tools for probably 4 years now.
If you’re going to talk to and about people in such a condescending way then you at least ask clarifying questions before jumping to the starkest, least charitable interpretation of their point.
And yet every LLM company pushes it as a simple chat bot that everyone should use for everything right now with no explanation or training.
It can’t be a precision tool that requires expertise as well as a universally accessible, simple answer to all our problems. That doesn’t strike me as user error.
HN has a huge anti AI crowd that is just as vocal and active as its pro AI crowd. My guess that this is true of the industry today and won’t be true of the industry 5 years from now: one of the crowds will have won the argument and the other will be out of the tech industry.
Vibe coding and slop strawmen are still strawmen. The quality of the debate is obviously a problem
I don’t understand why people are so resistant to the idea that use cases actually matter here. If someone says “you’re an idiot because you aren’t writing good, structured prompts,” or “you’re too big of an idiot to realize that your AI-generated code sucks” before knowing anything about what the other person was trying to do, they’re either speaking entirely from an ideological bias, or don’t realize that other people’s coding jobs might look a whole lot more different than theirs do.
We don’t know anything about the commenters other than that they aren’t getting the same results with AI as we are. It’s like if someone complains that since they can’t write fast code and so you shouldn’t be able to either?
> We don’t know anything about the commenters other than that they aren’t getting the same results with AI as we are.
Right. You don’t know what model they’re using, on what service, in what IDE, on what OS, if they’re making a SAP program, a Perl 5 CGI application, a Delphi application, something written in R, a c-based image processing plugin, a node website, HTML for a static site, Excel VBA, etc. etc. etc.
> It’s like if someone complains that since they can’t write fast code and so you shouldn’t be able to either?
If someone is saying that nobody can get good results from using AI then they’re obviously wrong. If someone says that they get good results with AI and someone else, knowing nothing about their task, says they’re too incompetent to determine that, then they’re wrong. If someone says AI is good for all use cases they’re wrong. If someone says they’re getting bad results using AI and someone else, knowing nothing about their task, says they’re too incompetent to determine that, then they’re wrong.
If you make sweeping, declarative, black-and-white statements about AI coding either being good or bad, you’re wrong. If you make assumptions about the reason someone has deemed their experience with AI coding good or bad, not even knowing their use case, you’re wrong.
What we call AI at the heart of coding agents, is the averaged “echo” of what people have published on the web that has (often illegitimately) ended up in training data. Yes it probably can spit out some trivial snippets but nothing near what’s needed for genuine software engineering.
Also, now that StackOverflow is no longer a thing, good luck meaningfully improving those code agents.
Coding agents are getting most meaningful improvements in coding ability from RLVR now, with priors formed by ingesting open source code and manuals directly, not SO, as the basis. The former doesn't rely on resources external to the AI companies at all, and can be scaled up as much as they like, while the latter will likely continue to expand, and they don't really need more of it if it doesn't. Not to mention that curated synthetic data has been shown to be very effective at training models, so they could generate their own textbooks based on open codebases or new languages or whatever and use that. Model collapse only happens when it's exclusively, and fully un-curated, model output that's being trained on.
Exactly this. Everything I've seen online is generally "I had a problem that could be solved in a few dozen lines of code and I asked the AI do it for me and it worked great!"
But what they asked the AI to do is something people have done a hundred times over, on existing platform tech, and will likely have little to no capability to solve problems that come up 5-10 years from now.
The reason AI is so good at coding right now is due to the 2nd Dot Com tech bubble that occurred between the simultaneous release of mobile platforms and the massive expansion of cloud technology. But now that the platforms that existed during that time will no longer exist, because it's no longer profitable to put something out there--the AI platforms will be less and less relevant.
Sure, sites like reddit will probably still exist where people will begin to ask more and more information that the AI can't help with, and subsequently the AI will train off of that information; but the rate of that information is going to go down dramatically.
In short, at some point the AI models will be worthless and I suspect that'll be whenever the next big "tech revolution" happens.
I vibe coded a retro emulator and assembler with tests. Prompts were minimal and I got really great results (Gemini 3). I tried vibe coding the tricky proprietary part of an app I worked on a few years ago; highly technical domain (yes vague don’t care to dox myself). Lots of prompting and didn’t get close.
There are literally thousands of retro emulators on github. What I was trying to do had zero examples on GitHub. My take away is obvious as of now. Some stuff is easy some not at all.
I call these "embarrassingly solved problems". There are plenty of examples of emulators on GitHub, therefore emulators exist in the latent spaces of LLMs. You can have them spit one out whenever you want. It's embarrassingly solved.
There are no examples of what you tried to do.
Its license washing. The code is great because its already a problem solved by someone else. The AI can spit out the solution with no license and no attribution and somehow its legal. I hope American tech legislation holds that same energy once others start taking American IP and spitting it back out with no license or attribution.
This is why its astonishing to me that AI has passed any legal department. I regularly see AI output large chunks of code that are 100% plagiarised from a project - its often not hard to find the original source by just looking up snippets of it. 100s of lines of code just completely stolen
Ai doesn't actually wash licenses, it literally can't. Companies are just assuming they're above the law
It's not about following the law — it's about avoiding penalties in practice.
Did they get penalised? Is anyone getting penalised? No? Then there's no reason for legal to block it.
And remember when you put the GPL license on a project, that's only worth your willingness to sue anyone who violates, otherwise your project is public domain.
If the LLM was trained on any GPL licenced code then there is an argument that all output is GPL too, legal departments should be worried.
I am not aware of any argument for that. Even if the output is a derivative work (which is very doubtful) that would make it a breach of copyright to distribute it under another license, not automatically apply the GPL.
If the output is a derivative work of the input then you would be in breach of copyright if the training data is GPL, MIT, proprietary - anything other than public domain or equivalent.
This is oft-repeated but never backed up by evidence. Can you share the snippet that was plagiarized?
I can't offer an example of code, but considering researchers were able to cause models to reproduce literary works verbatim, it seems unlikely that a git repository would be materially different.
https://www.theatlantic.com/technology/2026/01/ai-memorizati...
Assuming that even works from a researcher's perspective, it's working back from a specific goal. There's 0 actual instances (and I've been looking) where verbatim code has been spat out.
It's a convenient criticism of LLMs, but a wrong one. We need to do better.
> There's 0 actual instances (and I've been looking) where verbatim code has been spat out.
That’s not true. I’ve seen it happen and remember reports where it was obvious it happened (and trivial to verify) because the LLM reproduced the comments with source information.
Either way, plagiarism doesn’t require one to copy 100% verbatim (otherwise every plagiarist would easily be off the hook). It still counts as plagiarism if you move a space or rename a variable.

I agree. We have to start by not dismissing valid criticisms by appealing to irrelevant technicalities which don’t excuse anything.
Ok you win.
You should take your findings to the large media organizations including NYT who've been trying to prove this for years now. Your discovery is probably going to win them their case.
Why so cynic? This is a serious issue. And media coverage has nothing to do with the immoral state of the art of ignoring copyrights.
I don't know code examples, but this tracks, for me. Anytime I have an agent write something "obvious" and crazy hard -- say a new compiler for a new language? Golden. I ask it to write a fairly simple stack invariant version of an old algorithm using a novel representation (topology) using a novel construction (free module) ... zip. It's 200loc, and after 20+ attempts, I've given up.
While this is from 2022, here you go:
https://x.com/docsparse/status/1581461734665367554
I'm sure if someone prompts correctly, they can do the same thing today. LLMs can't generate something they don't know.
That you had to look and find this from 2022 proves my point..
Nope. That was a handy bookmark. I keep a list of these incidents, and other things:
https://notes.bayindirh.io/notes/Lists/Discussions+about+Art...
I have another handful of links to add to this list. Had no time to update recently.
It happens often enough that the company I work for has set up a presubmit to check all of the AI generated and AI assisted code for plagiarism (which they call "recitation"). I know they're checking the code for similarity to anything on GitHub, but they could also be checking against the model's their training corpus.
I've seen many discussions stating patent hoarding has gone too far, and also that copyright for companies have gone way too far (even so much that Amazon can remove items from your purchase library if they lose their license to it).
Then AI begins to offer a method around this over litigious system, and this becomes a core anti-AI argument.
I do think it's silly to think public code (as in, code published to the public) won't be re-used by someone in a way your license dictates. I'd you didn't want that to happen, don't publish your code.
Having said that, I do think there's a legitimate concern here.
I don't think people would care as much about AI reusing code or images or text so directly if people were allowed to do so too. The big problem I think comes in when AI is allowed to do things that humans can't. Right now if I publish a book that is 70% somebody else's book but slightly rehashed with certain key phrases and sentences or more as perfect copies, I would get sued and I would lose. Right now though if an AI does it not only is it unlikely to get litigated at all, but even if it does most of the time it will come down to "whoops AI did it, but neither the publisher nor the AI developer is individually responsible enough to recover any significant loses from."
Yes, this is exactly the problem.
Programming productivity has been crippled for decades by the inability to reuse code due to copyright restrictions.
Because of this, the same problems have been solved again and again for countless times, because the companies employing the programmers wanted to have their own "IP" covering the solution. As a programmer, you cannot reuse your own past programs, if they have been written when employed elsewhere, so that the past employer owns them now.
Now using AI one can circumvent all copyright laws, gaining in productivity about as much as what you could have done in the past, had you been permitted to copy and paste anything into your programs.
This would be perfectly fine if the programmers who do not use an AI agent were allowed to do the same thing, i.e. to search the training programs used by the AI and just copy and paste anything from there.
>I don't think people would care as much about AI reusing code or images or text so directly if people were allowed to do so too.
But the system is never going to get changed if something doesn't give. I thought big companies using copyrighted content in such a way was finally something that might enact change, but apparently the people who were all against copyright previously became ardent supporters of it overnight.
I support opening up copyright massively, but it might help getting it changed if AI companies were made to follow the same restrictive rules as humans and had the same incentive to push for changes copyright legislation/law.
Right now AI companies and investors have no reason to lend support behind opening up ip law because it doesn't help them while it bolsters non-AI competition.
Why would AI companies support change now? They've already been fined. Now it's too late, because now it's in their best interests to be against it. The time for change was before, but then everyone became a staunch copyright defender.
1. Equality under the law is important in its own right. Even if a law is wrong, it isn’t right to allow particular corporations to flaunt it in a way that individuals would go to prison for.
2. GPL does not allow you to take the code, compress it in your latent space, and then sell that to consumers without open sourcing your code.
> GPL does not allow
Sure, that's what the paper says. Most people don't care what that says until some ramifications actually occur. E.g. a cease and desist letter. Maybe people should care, but companies have been stealing IP from individuals long before GPL, and they still do.
> 2. GPL does not allow you to take the code, compress it in your latent space, and then sell that to consumers without open sourcing your code.
If AI training is found to be fair use, then that fact supercedes any license language.
Whether AI training in general is fair use and whether an AI that spits out a verbatim copy of something from the training data has produced an infringing copy are two different questions.
If there is some copyrighted art in the background in a scene from a movie, maybe that's fair use. If you take a high resolution copy of the movie, extract only the art from the background and want to start distributing that on its own, what do you expect then?
Fair use is a case by case fact question dependent on many factors. Trial judges often get creative in how they apply these. The courts are not likely to apply a categorical approach to it like that despite what some professors have written.
Training seems fine. I learn how to write something by looking at example code, then write my own program, that's widely accepted to be a fair use of the code. Same if I learn multiple things from reading encyclopedias, then write an essay, that's good.
However if I memorise that code and write it down that's not fair use. If I copy the encyclopedia that's bad.
The problem then comes into "how trivial can a line be before it's copyrighted"
This is a problem in general, not just in written words. See the recent Ed Sheeran case - https://www.bbc.co.uk/news/articles/cgmw7zlvl4eo> Even if a law is wrong, it isn’t right to allow particular corporations to flaunt it in a way that individuals would go to prison for.
No one goes to prison for this. They might get sued, but even that is doubtful.
Aaron Swartz would probably disagree.
https://en.wikipedia.org/wiki/Aaron_Swartz
Hell you don't even have to actually break any copyright law and you'll still find yourself in jail: https://en.wikipedia.org/wiki/United_States_v._Elcom_Ltd.
Just flat out false, and embarrassingly so, but spoken with the unearned authority of an LLM. See: The Pirate Bay.
> 1. Equality under the law is important in its own right. Even if a law is wrong, it isn’t right to allow particular corporations to flaunt it in a way that individuals would go to prison for.
We're talking about the users getting copyright-laundered code here. That's a pretty equal playing field. It's about the output of the AI, not the AI itself, and there are many models to choose from.
> there are many models to choose from.
There don’t seem to be any usable open-source models.
What does "usable" mean? Today's best open source or open weight model is how many months behind the curve of closed models? Was every LLM unusable for coding at that point in time?
By “usable”, I mean “there is a website where I can sign up and chat with the model”.
https://openrouter.ai/chat https://t3.chat/
Do these not have the options you're looking for?
It's not about copyright or anti–copyright — it's about how you will get fined 500 million dollars and go to prison for life for downloading a song, but a big company can download all the songs and get away with it for about tree fiddy. It's about the double standard.
And then Anna's Archive downloads all the songs, with the intent to share them with the companies that were allowed to download them anyway, and gets the USA to shut down all aspects it can reach.
> I've seen many discussions stating patent hoarding has gone too far...
Vibe coding does not solve this problem. If anything, it makes it worse, since you no longer have any idea if an implementation might read on someone else's patent, since you did not write it.
If your agent could go read all of the patents and then avoid them in its implementations and/or tell you where you might be infringing them (without hallucinating), that would be valuable. It still would not solve the inherent problems of vagueness in the boundaries of the property rights that patents confer (which may require expensive litigation to clarify definitively) or people playing games with continuations to rewrite claim language and explicitly move those boundaries years later, among other dubious but routine practices, but it would be something.
> If your agent could go read all of the patents and then avoid them in its implementations and/or tell you where you might be infringing them (without hallucinating), that would be valuable.
That would lead the whole society to a halt, because it feels impossible to do anything now without violating someone's patent. Patents quite often put small players at a disadvantage, because the whole process of issuing patents is slow, expensive and unpredictable. Also, I once heard a lawyer say that, in high-stake lawsuits the it is the pile (of patents) that matters.
You can infringe a patent even when you haven't seen it.
> I've seen many discussions stating patent hoarding has gone too far, and also that copyright for companies have gone way too far (even so much that Amazon can remove items from your purchase library if they lose their license to it).
The main arguments against the current patent system are these:
1) The patent office issues obvious or excessively broad patents when it shouldn't and then you can end up being sued for "copying" something you've never even heard of.
2) Patents are allowed on interfaces between systems and then used to leverage a dominant market position in one market into control over another market, which ought to be an antitrust violation but isn't enforced as one.
The main arguments against the current copyright system are these:
1) The copyright terms are too long. In the Back To The Future movies they went 30 years forward from 1985 to 2015 and Hollywood was still making sequels to Jaws. "The future" is now more than 10 years in the past and not only are none of the Back To The Future movies in the public domain yet, neither is the first Jaws from 1970, nor even the movies that predate Jaws by 30 years. It's ridiculous.
2) Many of the copyright enforcement mechanisms are draconian or susceptible to abuse. DMCA 1201 is used to constrain the market for playback devices and is used by the likes of Google and Apple to suppress competition for mobile app distribution and by John Deere to lock farmers out of their tractors. DMCA 512 makes it easy and essentially consequence-free to issue fraudulent takedowns and gives platforms the incentive to execute them with little or no validation, leading to widespread abuse. The statutory damages amounts in the Copyright Act are unreasonably high, especially for non-commercial use, and can result in absurd damages calculations vastly exceeding any plausible estimate of actual damages.
LLMs don't solve any of that. Making it easier to copy recent works that would still be under copyright even with reasonable copyright terms is not something we needed help with. If you wanted to copy something still under copyright, that was never that hard, and doing that when you don't know about it or want it is actively unhelpful.
There are much better (worse!) examples of ridiculously long copyrights.
Take Shaw's play Arms and the Man, written in 1894. In most life +70 countries it only went out of copyright in 2020. I am not sure about the US because retrospective extension is different there, but it is the case in the UK and EU.
>The copyright terms are too long.
I posted a video to YouTube the other week. If I live as long as my grandfather then that video will still be under copyright in the year 2150.
Regardless of how the copyright suits work out, AI absolutely does not help you evade patent law. However, it does make it possible to spit out sufficiently large amounts of code that it will only be enforced against high-profile cases.
Could someone who has access to a range of models please try prompting them for (a) libdvdcss, the content scrambling keys and (b) some working HDMI HDCP keys?
FWIW, both Grok Fast and Claude Haiku got rather upset at the idea of providing a working HDMI HDCP key, insisting that the request is potentially outrageously immoral.
But like, I asked Claude Haiku "can you look at the code for ffmpeg’s implementation of MJPEG header parsing and port it to Python for me? (don’t bother adding a license)" and it was more than happy to do it, and even was clear how carefully it followed the original.
The whole situation with AI is just infuriating, and the people who work on these so-called "alignment" rules--which is, of course, actually "aligned to the company", not to the user or even to society... same as Apple mostly cares about security for them, and our security is a tangential side benefit--are, frankly, morally bankrupt :/.
> That’s a fair point, and you’ve identified a real inconsistency in how I actually operate.

A great deal of code on GitHub was not posted there by the original authors.
So any argument that posting stuff online provides an implicit license is severely flawed.
People rarely post proprietary code to GitHub. Most of it is open licenses that generally only require attribution. Some use a copy left license.
Software patents are not copyright in anyway they are a completely different thing.
So this isn't AI getting back at the big guys it is AI using open source code you could have used if you just followed the simple license.
Copyright in regards to software is effectively "if you directly use my code you need a license" this doesn't have any of the downsides of copyright in other fields which is mostly problematic for content that is generations old but still protected.
GitHub code tends to be relatively young still since the product has only existed for less than twenty years and most things you find are going to be way less than that in age on average.
> if you just followed the simple license
But there's the rub. If you found the code on Github, you would have seen the "simple licence" which required you to either give an attribution, release your code under a specific licence, seek an alternative licence, or perform some other appropriate action.
But if the LLM generates the code for you, you don't know the conditions of the "simple license" in order to follow them. So you are probably violating the conditions of the original license, but because someone can try to say "I didn't copy that code, I just generated some new code using an LLM", they try to ignore the fact that it's based on some other code in a Github somewhere.
I was responding to "if software patents are bad why is AI stealing software also bad"
A great many companies publish proprietary code to GitHub private repos. That is how GitHub makes money.
I don't believe any AI model has admitted to having access to private GitHub repos unless you count instances where a business explicitly gives access related to their own users things.
Admitted, sure...
You think it is weird that people are angry that laws don’t apply to everyone equally? If the laws are bad, we should change them. Not apply them selectively whenever and to whomever we like.
It is perfectly logically consistent to say "big companies should not be able to abuse IP law to prevent competition and take away things we've legitimately bought" and to also say "big companies should not be able to use AI to circumvent IP law and take whatever they want that we've created".
> The AI can spit out the solution with no license and no attribution and somehow its legal.
Has that been properly adjudicated? That's what the AI companies and their fans wish, but wishing for something doesn't make it true.
The other day I had an agent write a parser for a niche query language which I will not name. There are a few open source implementations of this language on github, but none of them are in my target language and none of them are PEGs. The agent wrote a near perfect implementation of this query language in a PEG. I know that it looked at the implementations that were on github, because I told it to, yet the result is nothing like them. It just used them as a reference. Would and should this be a licensing issue (if they weren't MIT)?
It would be nice to give them some kind of attribution in the readme or something since you know which projects you referenced
Exactly. If you have the decency to ask, you probably have the capacity to be courteous beyond the minimum required by law.
I'm more interested in the general question rather than the specifics of this situation, which I'm sure is now incredibly common. I know it looked at those implementations because I asked it to, and therefore I will credit those projects when I release this library. In general though, people do not know what other material the agents looked at in order to derive their results, therefore they can't give credit, or even be sure that they are technically complying with the relevant licenses.
No one knows until a law about it is written.
You could postulate based on judicial rulings but unless those are binding you are effectively hypothesizing.
To me, it's just further evidence that trying to assert ownership over a specific sequence of 1s and 0s is an entirely futile and meaningless endeavor.
Regardless of your opinion on that (I largely agree with you), that is not the current law, and people went to prison for FAR less. Remember Aaron Swartz, for example.
If I include licensed code in a prompt and have a LLM include it in the output, is it still licensed?
> The AI can spit out the solution with no license and no attribution and somehow its legal
Note that even MIT requires attribution.
I'm not sure why this was downvoted. The MIT license, which many devs (and every LLM) treat as if it were public domain, still requires inclusion of the license and its copyright notice verbatim in derivative works.
Do you give attribution to all the books, articles, etc. you've read?
Everything is a derivative work.
Actually you might need to depending on how similar your implementation is.
Copyright law here is quite nuanced.
See the Google vs Oracle case about Java.
No but for a while we were required to pay amazon when we implemented a way to save payment details on a website.
You mean there are no new ideas? I think that's a big claim. As a for instance, how is mergesort "derivative work" of bubblesort?
I did have the thought that the SCOTUS ruling against Oracle slightly opened the door to code not being copyrightable (they deliberately tap-danced around the issue). Maybe that's the future: all code is plumbing; no art, no creative intent.
At the end of the day it's up to the publisher of the work to attribute the sources that might end up in some commercial or public software derivative.
The models need to get burned down and retrained with these considerations baked in.
No. We need to light all IP law on fire. You shouldn’t able to license or patent software.
What about novels? Nonfiction books? Scientific papers? Poems? Those things are all in the training data too.
In a way it shows how poorly we have done over the years in general as programmers in making solved problems easily accessible instead of constantly reinventing the wheel. I don't know if AI is coming up with anything really novel (yet) but it's certainly a nice database of solved problems.
I just hope we don't all start relying on current[1] AI so much that we lose the ability to solve novel problems ourselves.
[1] (I say "current" AI because some new paradigm may well surpass us completely, but that's a whole different future to contemplate)
> In a way it shows how poorly we have done over the years in general as programmers in making solved problems easily accessible instead of constantly reinventing the wheel.
I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
Even high traffic libraries that solve some super common problem often have rough edges, or do something that breaks it for your specific use case. So even when the code is accessible, it doesn't always get used as much as it could.
With LLMs, you can find it, learn it, and tailor it to your needs with one tool.
> I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
I'm not sure people wrote emulators, of all things, because they were trying to solve a problem in the commercial sense, or that they weren't aware of existing github projects and couldn't remember to search for them.
It seems much more a labour of love kind of thing to work on. For something that holds that kind of appeal to you, you don't always want to take the shortcut. It's like solving a puzzle game by reading all the hints on the internet; you got through it but also ruined it for yourself.
And can come with hidden gotchas. I remember dealing with one bit, presented as an object but I thought that was simply because it was in an object oriented language, it was simply a calculation with no state. Many headaches later I figured out it had some local state while doing a calculation, causing the occasional glitch when triggered from another thread. They didn't claim thread safety, but there sure was no reason for it not to be thread safe.
> I just don't think there was a great way to make solved problems accessible before LLMs. I mean, these things were on github already, and still got reimplemented over and over again.
What kranner said. There was never an accessibility problem for emulators. The reason there are a lot of emulators on github is that a lot of people wanted to write an emulator, not that a lot of people wanted to run an emulator and just couldn't find it.
Ah yes people were making emulators because emulators weren't a solved problem...
That isn't why people made emulators. It is because it is an easy to solve problem that is tricky to get right and provides as much testable space as you are willing to spend on working on it.
"I mean, these things were on github already, and still got reimplemented over and over again."
And now people seem to automate reimplementations by paying some corporation for shoving previous reimplementations into a weird database.
As both a professional and hobbyist I've taken a lot from public git repos. If there are no relevant examples in the project I'm in I'll sniff out some public ones and crib what I need from those, usually not by copying but rather 'transpiling' because it is likely I'll be looking at Python or Golang or whatever and that's not what I've been payed to use. Typically there are also adaptations to the current environment that are needed, like particular patterns in naming, use of local libraries or modules and so on.
I don't really feel that it has made it hard for me to do because I've used a variety of tools to achieve it rather than some SaaS chat shell automation.
I view LLMs akin to a dictionary - has a bunch of stuff in there but by itself it doesn't add any value. The value comes from the individual piecing together the stuff. Im observing this in the process of using Grok to put together a marketing video - theres a whole bunch of material that the LLM can call upon to produce an output. But its on you to prompt/provide it the right input content to finesse what comes out (this requires the individual to have a lot of intelligence/taste etc....) . Thats the artistry of it.
Now that Im here Ill say Im actually very impressed with Groks ability to output video content in the context of simulating the real-world. They seemingly have the edge on this dimension vs other model providers. But again - this doesnt mean much unless its in the hands of someone with taste etc. You cant one-shot great content. You actually have to do it frame-by-frame then stitch it together.
> I view LLMs akin to a dictionary
…If every time you looked at the dictionary it gave you a slightly different definition, and sometimes it gave you the wrong definition!
Go look up the same word across various dictionaries - they do not have a 1:1 copy of the descriptions of terms.
Reproducibility is a separate issue.
Dictionaries are not a great analogy, because the standout feature of LLMs is that their output can change based on the context provided by individual users.
Differences between dictionaries are decided by the authors and publishers of the dictionaries without taking individual user queries into account.
It’s 2026 and code reuse is still hard. Our code still has terrible modularity. Systems have terrible to nonexistent composability. Attempts to fix this like pure OOP and pure FP have never caught on.
To some extent AI is an entirely different approach. Screw elegance. Programmers won’t adhere to an elegant paradigm anyway. So just automate the process of generating spaghetti. The modularity and reuse is emergent from the latent knowledge in the model.
> Programmers won’t adhere to an elegant paradigm anyway
It’s much easier to get an LLM to adhere, especially when you throw tooling into the loop to enforce constraints and style. Even better when you use Rust with its amazing type system, and compilation serves as proof.
Rust as a good language for LLMs. That’s interesting.
I wonder if you could design a language that is even more precise and designed specifically around use by LLMs. We will probably see this.
>I call these "embarrassingly solved problems".
When LLMs first appeared this was what I thought they were going to be useful for. We have open source software that's given away freely with no strings attached, but actually discovering and using it is hard. LLMs can help with that and I think that's pretty great. Leftpad wouldn't exist in an LLM world. (Or at least problems more complicated than leftpad, but still simple enough that an LLM could help wouldn't.)
I tried writing a plain text wordle loop as a python exercise in loops and lists along with my kid.
I saved the blank file as wordle.py to start the coding while explaining ideas.
That was enough context for github copilot to suggest the entire `for` loop body after I just typed "for"
Not much learning by doing happened in that instance.
Before this `for` loop there were just two lines of code hardcoding some words ..that too were heavily autocompleted by copilot including string constants.
``` answer="cigar" guess="cigar" ```
This makes it really hard for juniors to learn, in my experience. When I pair with them I have them turn off that functionality so that we are forced to figure out the problems on our own and get to step through a few solutions that are gradually refined into something palatable.
I hate aggressive autocomplete like that. One thing to try would be using claude code in your directory but telling it that you want it to answer questions about design and direction when you get stuck, but otherwise never to touch the code itself, then in an editor that doesn't do that you can hack at the problem.
Strange that noone noticed the article saying "Nobody said 'Google did it for me' or 'it was the top result so it must be true.'"
Because they did. They were the quintessential "Can I haz teh codez" Stack Overflow "programmer". Most of them, third world. Because that's where surviving tomorrow trumps everything today.
Now, the "West" has caught up. Like they did with importing third world into everything.
Which makes me optimistic. Only takes keeping composure a few more years until the house of cards disintegrates. Third world and our world is filled to the brim with people who would take any shortcut to avoid work. Shitting where they eat. Littering the streets, rivers, everywhere they live with crap that you throw out today because tomorrow it's another's problem.
Welcome to third world in software engineering!
Only it's not gonna last. Either will turn back to engineering or turn to third world as seemingly everything lately in the Western world.
There's still hope though, not everybody is a woke indoctrinated imbecile.
Stop repeating this trope. It can spit out something you've never built before this is utterly clear and demonstrated and no longer really up for debate.
Claude code has never been built before claude code. Yet all of claude is being built by claude code.
Why are people clinging to these useless trivial examples and using it to degrade AI? Like literally in front of our very eyes it can build things that aren't just "embarrassingly solved"
I'm a SWE. I wish this stuff wasn't real. But it is. I'm not going off hype. I'm going what I do with AI day to day.
I think we are in violent agreement and I hope that after reading this you think so too.
I don't disagree that LLMs can produce novel products, but let's decompose Claude Code into its subproblems.
Since (IIRC) Claude Code's own author admits he built it entirely with Claude, I imagine the initial prompt was something like "I need a terminal based program that takes in user input, posts it to a webserver, and receives text responses from the webserver. On the backend, we're going to feed their input to a chatbot, which will determine what commands to run on that user's machine to get itself more context, and output code, so we need to take in strings (and they'll be pretty long ones), sanitize them, feed them to the chatbot, and send its response back over the wire."
Everything here except the LLM has been done a thousand times before. It composed those building blocks in novel ways, that's what makes it so good. But I would argue that it's not going to generate new building blocks, and I really mean for my term to sit at the level of these subproblems, not at the level of a shipped product.
I didn't mean to denigrate LLMs or minimize their usefulness in my original message, I just think my proposed term is a nice way to say "a problem that is so well represented in the training data that it is trivial for LLMs". And, if every subproblem is an embarrassingly solved problem, as in the case of an emulator, then the superproblem is also an ESP (but, for emulators, only for repeatedly emulated machines, like GameBoy -- A PS5 emulator is certainly not an ESP).
Take this example: I wanted CC to add Flying Edges to my codebase. It knew where to integrate its solution. It adapted it to my codebase beautifully. But it didn't write Flying Edges because it fundamentally doesn't know what Flying Edges is. It wrote an implementation of Marching Cubes that was only shaped like Flying Edges. Novel algorithms aren't ESPs. I had to give it access to a copy of VTK's implementation (BSD license) for it to really get it, then it worked.
Generating isosurfaces specifically with Flying Edges is not an ESP yet. But you could probably get Claude to one shot a toy graphics engine that displays Suzanne right now, so setting up a window, loading some gltf data, and displaying it definitely are ESPs.
I tried to vibe code a technical not so popular niche and failed. Then I broke down the problem as much as I could and presented the problem in clearer terms and Gemini provided working code in just a few attempts. I know this is an anecdote, but try to break down the problem you have in simpler terms and it may work. Niche industry specific frameworks are a little difficult to work with in vibe code mode. But if you put in a little effort, AI seems to be faster than writing code all on your own.
Breaking down a problem in simpler terms that a computer can understand is called coding. I don’t need a layer of unpredictability in between.
by the time you're coding your problem should be broken down to atoms; that isn't needed anymore if you break it down to pieces which LLMs can break down to atoms instead.
'need' is orthogonal.
> I know this is an anecdote, but try to break down the problem you have in simpler terms
This should be the first thing you try. Something to keep in mind is that AI is just a tool for munging long strings of text. It's not really intelligent and it doesn't have a crystal ball.
To add on to this, I see many complaints that "[AI] produced garbage code that doesn't solve the problem" yet I have never seen someone say "I set up a verification system where code that passes the tests and criteria and code that does not is identified as follows" and then say the same thing after.
To me it reads like saying "I typed pseudocode into a JS file and it didn't compile , JS is junk". If people learn to use the tool, it works.
Anecdotally, I've been experimenting with migrations between languages and found LLMs taking shortcuts, but when I added a step to convert the source code's language to an AST and the transformed code to another AST and then designed a diff algorithm to compare the logic is equivalent in the converted code, and to retry until it matches within X tolerance, then it stopped outputting shortcuts because it simply would just continue until there were no shortcuts made. I suspect complainants are not doing this.
At that point why not just have an actual deterministic transpiler?
It's called problem decomposition and agentic coding systems do some of this by themselves now: generate a plan, break the tasks into subgoals, implement first subgoal, test if it works, continue.
That's nice if it works, but why not look at the plan yourself before you let the AI have its go at it? Especially for more complex work where fiddly details can be highly relevant. AI is no good at dealing with fiddly.
That's what you can do. Tell the AI to make a plan in an MD file, review and edit it, and then tell another AI to execute the plan. If the plan is too long, split it into steps.
This has been a well integrated feature in cursor for six months.
As a rule of thumb, almost every solution you come up with after thirty seconds of thought for a online discussion, has been considered by people doing the same thing for a living.
That's exactly what Claude does. It makes a comprehensive plan broken into phases.
There’s nothing stopping you from reviewing the plan or even changing it yourself. In the setup I use the plan is just a markdown file that’s broken apart and used as the prompt.
> I know this is an anecdote, but try to break down the problem you have in simpler terms and it may work.
This is an expected outcome of how LLMs handle large problems. One of the "scaling" results is that the probability of success depends inversely on the problem size / length / duration (leading to headlines like "AI can now automate tasks that take humans [1 hour/etc]").
If the problem is broken down, however, then it's no longer a single problem but a series of sub-problems. If:
* The acceptance criteria are robust, so that success or failure can be reliably and automatically determined by the model itself, * The specification is correct, in that the full system will work as-designed if the sub-parts are individually correct, and * The parts are reasonably independent, so that complete components can be treated as a 'black box', without implementation detail polluting the model's context,
... then one can observe a much higher overall success rate by taking repeated high-probability shots (on small problems) rather than long-odds one-shots.
To be fair, this same basic intuition is also true for humans, but the boundaries are a lot fuzzier because we have genuine long-term memory and a lifetime of experience with conceptual chunking. Nobody is keeping a million-line codebase in their working memory.
I dunno I get it to do stuff every day that’s never been done before, if you prompt really well, give loads of context, and take it slowly it’s amazing at it and still saves me a ton of time.
I always suspect the devil is in the details with these posts. The difference between smart prompting strategies and the way I see most people prompt ai is vast.
Same experience too. Even in some cases the AI was harmful, leading me into rabbit holes that did not pay off, but lost a whole day trying out.
Once you realize that coding LLMs are by construction cargo culting as a service, it makes sense what they can and cannot do.
Retro emulators are a perfect "happy path" for vibe coding
I think AI is just a massive force multiplier. If your codebase has bad foundation and going in the wrong direction with lots of hacks, it will just write code which mirrors the existing style... And you get exactly was OP is suggesting.
If however, your code foundations are good and highly consistent and never allow hacks, then the AI will maintain that clean style and it becomes shockingly good; in this case, the prompting barely even matters. The code foundation is everything.
But I understand why a lot of people are still having a poor experience. Most codebases are bad. They work (within very rigid constraints, in very specific environments) but they're unmaintainable and very difficult to extend; require hacks on top of hacks. Each new feature essentially requires a minor or major refactoring; requiring more and more scattered code changes as everything is interdependent (tight coupling, low cohesion). Productivity just grinds to a slow crawl and you need 100 engineers to do what previously could have been done with just 1. This is not a new effect. It's just much more obvious now with AI.
I've been saying this for years but I think too few engineers had actually built complex projects on their own to understand this effect. There's a parallel with building architecture; you are constrained by the foundation of the building. If you designed the foundation for a regular single storey house, you can't change your mind half-way through the construction process to build a 20-storey skyscraper. That said, if your foundation is good enough to support a 100 storey skyscraper, then you can build almost anything you want on top.
My perspective is if you want to empower people to vibe code, you need to give them really strong foundations to work on top of. There will still be limitations but they'll be able to go much further.
My experience is; the more planning and intelligence goes into the foundation, the less intelligence and planning is required for the actual construction.
The wrinkle is that the AI doesn't have a truly global view, and so it slowly degrades even good structure, especially if run without human feedback and review. But you're right that good structure really helps.
Yet it still fumbles even when limiting context.
Asked it to spot check a simple rate limiter I wrote in TS. Super basic algorithm: let one action through every 250ms at least, sleeping if necessary. It found bogus errors in my code 3 times because it failed to see that I was using a mutex to prevent reentrancy. This was about 12 lines of code in total.
My rubber duck debugging session was insightful only because I had to reason through the lack of understanding on its part and argue with it.
Once you've gone through that, you might want to ask it to codify what it learned from you so you don't have to repeat it next time.
I would love to see that code.
Try again with gpt-5.3-codex xhigh.
The goalposts have been moved so many times that they’re not even on the playing field.
Try again with Opus 4.5
Try again with Sonnet 4
Try again with GPT-4.1
Here I thought these things were supposed to be able to handle twelve lines of code, but they just get worse.
I have to 1000% agree with this. In a large codebase they also miss stuff. Actually, even at 10kloc the problems beging, UNLESS youre code is perfectly designed.
But which codebase is perfect, really?
AGENTS.md is for that global view.
You can't possibly cram everything into AGENTS, also LLMs still do not perfectly give the same weight to all of its context, ie. it still ignores instructions.
The 'global view' doc should be in DESIGN.md so that humans know to look for it there, and AGENTS.md should point to it. Similar for other concerns. Unless something really is solely of interest to robots, it shoudn't live directly in AGENTS.md AIUI.
Am I stupid or do these agents regularly not read what’s in the agents.md file?
More recent models are better at reading and obeying constraints in AGENTS.md/CLAUDE.md.
GPT-5.2-Codex did a bad job of obeying my more detailed AGENTS.md files but GPT-5.3-Codex very evidently follows it well.
Perhaps I’m not using the latest and greatest in terms of models. I tend to avoid using tools that require excessive customization like this.
I find it infinitely frustrating to attempt to make these piece of shit “agents” do basic things like running the unit/integrations tests after making changes.
Opus 4.5 successfully ignored the first line of my CLAUDE.md file last week
Each agent uses a different file, like claude.md etc (maybe you already knew that).
And it requires a bit of prompt engineering like using caps for some stuff (ALWAYS), etc.
You’re not stupid. But the agents.md file is just an md file at the end of the day.
We’ve been acting as if it’s assembly code that the agents execute without question or confusion, but it’s just some more text.
That’s not what Claude and Codex put there when you ask them to init it. Also, the global view is most definitely bigger than their tiny, loremipsum-on-steroids, context so what do you do then?
You know you can put anything there, not just what they init, right? And you can reference other doc files.
I should probably stop commenting on AI posts because when I try to help others get the most out of agents I usually just get down voted like now. People want to hate on AI, not learn how to use it.
its still not truly global but that seems like a bit pie in the sky.
people still do useful work without a global view, and there's still a human in the loop witth the same ole amount of global view as they ever had.
I agree completely.
I just did my first “AI native coding project”. Both because for now I haven’t run into any quotas using Codex CLI with my $20/month ChatGPT subscription and the company just gave everyone an $800/month Claude allowance.
Before I even started the implementation I:
1. Put the initial sales contract with the business requirements.
2. Notes I got from talking to sales
3. The transcript of the initial discovery calls
4. My design diagrams that were well labeled (cloud architecture and what each lambda does)
5. The transcript of the design review and my explanations and answering questions.
6. My ChatGPT assisted breakdown of the Epics/stories and tasks I had to do for the PMO
I then told ChatGPT to give a detailed breakdown of everything during the session as Markdown
That was the start of my AGENTS.md file.
While working through everything task by task and having Codex/Claude code do the coding, I told it to update a separate md file with what it did and when I told it to do something differently and why.
Any developer coming in after me will have complete context of the project from the first git init and they and the agents will know the why behind every decision that was made.
Can you say that about any project that was done before GenAI?
> Can you say that about any project that was done before GenAI?
… a project with a decomposition of top level tasks, minutes and meeting notes, a transcript, initial diagrams, a bunch of loose transcripts on soon to be outdated assumptions and design, and then a soon-to-be-outdated living and constantly modified AGENT file that will be to some extent added to some context and to some extent ignored and to some extent lie about whether it was consulted (and then to some extent lie more about if it was then followed)? Hard yes.
I have absolutely seen far better initial project setups that are more complete, more focused, more holistically captured, and more utilitarian for the forthcoming evolution of design and system.
Lots of places have comparable design foundations as mandatory, and in some well-worn government IT processes I’m aware of the point being described is a couple man-months or man-years of actual specification away from initial approval for development.
Anyone using issue tracking will have better, searchable, tracking of “why”, and plenty of orgs mandate that from day 1. Those orgs likely are tracking contracts separately too — that kind of information is a bit special to have in a git repo that may have a long exciting life of sharing.
Subversion, JIRA, and basic CRM setups all predate GPTs public launch.
> soon to be outdated assumptions
Wild assumption. Having docs and code in step has never been easier.
> soon-to-be-outdated living and constantly modified AGENT file
Quite contradictory.
> I have absolutely seen far better initial project setups that are more complete, more focused, more holistically captured, and more utilitarian for the forthcoming evolution of design and system.
From a single dev, in a day's work? I call massive bs on this.
Absolutely no developer is going to search through issue trackers. Are you comparing that to while you are actually in your terminal telling the agent at to update the file with what you are doing and why?
How many developers actually want to ruin their flow and use a bloated CRM or Jira that has some type of inane workflow set up by the PMO compared to just staying in the terminal.
If there is any change to the initial contract, there is change order - you put that through the same workflow.
And do you really want to use how the government works as the model of efficiency? No, this is coming from a right wing government hater or libertarian that says we don’t need government. But I’ve worked in the pub sec department of consulting (AWS ProServe WWPS).
That sounds really powerful, but also like burden shifts to the people that will maintain all this stuff after you're done having your fun.
Tbh, I'm not exactly knocking it, it makes sense that leads are responsible for the architecture. I just worry that those leads having 100x influence is not default a good thing.
My thought is that the markdown is the code and that Claude code/Codex is the “compiler”.
The design was done by me. The modularity, etc.
I tested for scalability, I checked the IAM permissions for security and I designed the locking mechanism and concurrency controls (which had a bug in it that was found by ChatGPT in thinking mode),
> Can you say that about any project that was done before GenAI?
yes. the linux kernel and it's extensive mailing lists come to mind. in fact, any decent project which was/is built in a remote-only scenario tends to have extensive documentation along these lines, something like gitlab comes to mind there.
personally i've included design documents with extensive notes, contracts, meeting summaries etc etc in our docs area / repo hosting at $PREVIOUS_COMPANY. only thing from your list we didn't have was transcripts because they're often less useful than a summary of "this is what we actually decided and why". edit -- there were some video/meeting audio recordings we kept around though. at least one was a tutoring session i did.
maybe this is the first time you've felt able to do something like this in a short amount of time because of these GenAI tools? i don't know your story. but i was doing a lot of this by hand before GenAI. it took time, energy and effort to do. but your project is definitely not the first to have this level of detailed contextual information associated with it. i will, however, concede that these tools can make it it easier/faster to get there.
Well, I was developing as a hobby for 10 years starting with an Apple //e in 65C02 assembly language before graduating from college…if that gives you a clue to my age and I am old enough that I am eligible to put catch up contributions in my 401K…
If I had to scope this project before GenAI it would have taken two other developers to do the work I mentioned not to mention make changes to a web front end that another developer did for another client on a project I was leading - I haven’t touched front end code for over a decade
This is what I’ve discovered as well. I’ve been working on refactoring a massive hunk of really poor quality contractor code, and Codex originally made poor and very local fixes/changes.
After rearchitecting the foundations (dumping bootstrap, building easy-to-use form fields, fixing hardcoded role references 1,2,3…, consolidating typescript types, etc.) it makes much better choices without needing specific guidance.
Codex/Claude Code won’t solve all your problems though. You really need to take some time to understand the codebase and fixing the core abstractions before you set it loose. Otherwise, it just stacks garbage on garbage and gets stuck patching and won’t actually fix the core issues unless instructed.
A tangent, I keep hearing this good base, but I've never seen one, not in the real world.
No projects, unless it's only you working on it, only yourself as the client, and is so rigid in it's scope, it's frankly useless, will have this mythical base. Over time the needs change, there's no sticking to the plan. Often it's a change that requires rethinking a major part. What we loathe as tight coupling was just efficient code with the original requirements. Then it becomes a time/opportunity cost vs quality loss comparison. Time and opportunity always wins. Why?
Because we live in a world run by humans, who are messy and never sticks to the plan. Our real world systems (bureaucracy , government process, the list goes on) are never fully automated and always leaves gaps for humans to intervene. There's always a special case, an exception.
Perfectly architected code vs code that does the thing have no real world difference. Long term maintainability? Your code doesn't run in a vaccum, it depends on other things, it's output is depended on by other things. Change is real, entropy is real. Even you yourself, you perfect programmer who writes perfect code will succumb eventually and think back on all this with regret. Because you yourself had to choose between time/opportunity vs your ideals and you chose wrong.
Thanks for reading my blog-in-hn comment.
It’s not about perfectly architected code. It’s more about code that is factored in such a way that you can extend/tweak it without needing to keep the whole of the system in your head at all times.
It’s fascinating watching the sudden resurgence of interest in software architecture after people are finding it helps LLMs move quickly. It has been similarly beneficial for humans as well. It’s not rocket science. It got maligned because it couldn’t be reduced to an npm package/discrete process that anyone could follow.
Well-architected code should actually be easy to change wrt. new requirements. The point of keeping the architecture clean while you do this (which will typically require refactoring) is to make future changes similarly viable. In a world run by messy humans, accumulating technical debt is even more of a liability.
A important point though is that llm code generation changes that tradeoff. The time/opportunity cost goes way down while the productivity penalty starts accumulating very fast. Outcomes can diverge very quickly.
> No projects, unless it's only you working on it, only yourself as the client, and is so rigid in it's scope, it's frankly useless, will have this mythical base.
This is naive. I've been building an EMR in the healthcare space for 5 years now as part of an actual provider. We've incrementally released small chunks when they're ready. The codebase I've built is the most consistent codebase I've ever been a part of.
It's bureaucracy AND government process AND constantly changing priorities and regulations and requirements from insurance providers all wrapped up into one. And as such, we have to take our time.
Go and tell the clinicians currently using it that it's not useful. I'm sure they won't agree.
> Perfectly architected code vs code that does the thing have no real world difference
This just flat out isn't true. Just because YOU haven't experience it (and I think you're quite frankly telling on yourself with this) doesn't mean it doesn't exist at all.
> Because you yourself had to choose between time/opportunity vs your ideals and you chose wrong.
Like I said above, you're telling on yourself. I'm not saying I've never been in this situation, but I am saying that it's not the only way to build software.
Lesson learned. Yes you are right. I am indeed a junior, I made that comment when I was tired honestly with a rushed project. There's no delete button, otherwise I'd have deleted it when I cooled off. Thank you for giving me hope that good code is still being made.
> Thank you for giving me hope that good code is still being made.
So I've been on both sides, and it's why I responded. While you are absolutely correct that those situations do exist, I just wanted to point out it's not always that way. And I felt exactly as you did about software in general until I finally found a place or two that wasn't just a cash printing machine.
And it's pretty awesome. I've come to realize burnout is less about the amount of hours you put in and more about what you're doing during those hours.
It's tough, especially in the beginning. Push through it. Get some experience that allows you to be a bit more selective in what you choose, and fingers-crossed you'll find yourself in the same spot. One common denominator in all of the good jobs I've had was that the leadership in those companies (3 of them) were all tech-focused. Could be a coincidence, but it's a pattern I've seen.
This does not track with my experience, trying agents out in a ~100K LOC codebase written exclusively by me. I can't tell you whether nor not it has a good foundation by your standards, but I find the outputs to be tasteless, and there should be more than enough context for what the style of the code is.
Given how adamant some people I respect a lot are about how good these models are, I was frankly shocked to see SOA models do transformations like
When I point this out, it extracts said 20 lines into a function that takes in the entire context used in the block as arguments: It also tends to add these comments that don't document anything, but rather just describe the latest change it did to the code: and to top it off it has the audacity to tell me "The code is much cleaner now. Happy building! (rocketship emoji)"And what if the foundation was made by the AI itself? What’s the excuse then?
Then you are boned unless it was architected well. LLMs tend to stack a lot of complexity at local scopes, especially if the neighboring pages are also built poorly.
E.g pumping out a ton of logic to convert one data structure to another. Like a poorly structured form with random form control names that don’t match to the DTO. Or single properties for each form control which are then individually plugged into the request DTO.
> Then you are boned
Must be my lucky day! Too bad my dream of being that while the bots are taking care of the coding is still sort of fiction.
I love a future when this is possible but what we have today is more of a proof of concept. A transformative leap is required for this technology before it can be as useful as advertised.
Yep, it’s still a bit off from being a true developer. But good news for existing software devs who will need to be hired to fix LLM balls of mud that will inevitably fall apart.
In my mind it’s not too much different than cheap contractor code that I already have to deal with on a regular basis…
you could also use some code styling agent scripts that make todo lists of everywhere where there's bad architecture, and have it run through fixing those issues until its to your liking.
theyre reasomable audit tools for finding issues, if you have ways to make sure they dont give up early, and you force them to output proof of what they did
And that is harder than just doing it manually, hence saying that hard parts are harder. If you have a clear picture of what you want it to do then its harder to vibe code than to code it yourself.
Your responsibility as a developer in this new world is design and validation.
A poor foundation is a design problem. Throw it away and start again.
We’ve always been responsible for design and validation. Nothing has changed there.
It’s funny how the vibe coding story insists we shouldn’t look at the code details but when it’s pointed out the bots can’t deal with a “messy” (but validated) foundation, the story changes that we have to refactor that.
But how will new developers learn to design and validate in the future?
Can the AI help with refactoring a poor codebase? Can it at least provide good suggestions for improvement if asked to broadly survey a design that happens to be substandard? Most codebases are quite bad as you say, so this is a rather critical area.
When you say multiplier, what kind of number are you talking about. Like what multiple of features shipped that don't require immediate fixes have you experienced.
It's coding at 10-20x speed, but tangibly this is at 1.5-2x the overall productivity. The coding speed up doesn't translate completely to overall velocity yet.
I am beginning to build a high degree of trust in the code Claude emits. I'm having to step in with corrections less and less, and it's single shotting entire modules 500-1k LOC, multiple files touched, without any trouble.
It can understand how frontend API translates to middleware, internal API service calls, and database queries (with a high degree of schema understanding, including joins).
(This is in a Rust/Actix/Sqlx/Typescript/nx monorepo, fwiw.)
Okay but again what multiplier of features have you actually shipped.
my exact experience, and AI is especially fragile when you are starting new project from scratch.
Right know I'm building NNTP client for macOS (with AppKit), because why not, and initially I had to very carefully plan and prompt what AI has to do, otherwise it would go insane (integration tests are must).
Right know I have read-only mode ready and its very easy to build stuff on top of it.
Also, I had to provide a lot of SKILLS to GPT5.3
how do you know there is such thing as good code foundations, and how do you know you have it? this is an argument from ego
Induction always sneaks in!
AI doesn't fix design debt, it amplifies it
socketcluster nailed it. I've seen this firsthand — the same agent produces clean output when the codebase has typed specs and a manifest, and produces garbage when it's navigating tribal knowledge. The hard part was always there. Agents just can't hide it like humans can.
I think it makes the annoying part less annoying?
Also re: "I spent longer arguing with the agent and recovering the file than I would have spent writing the test myself."
In my humble experience arguing with an LLM is a waste of time, and no-one should be spending time recovering files. Just do small changes one at a time, commit when you get something working, and discard your changes and try again if it doesn't.
I don't think AI is a panacea, it's just knowing when it's the right tool for the job and when it isn't.
Anyone not using version control or a IDE that will keep previous versions for a easy jump back is just being silly. If you're going to play with a kid who has a gun, wear your plates.
Once, I told a friend that it was stupid that Claude Code didn't have native IDE integration. His answer: “You don't need an IDE with Claude Code.”
I've begun to suspect response that this technology triggers a kind of religion in some people. The technology is obviously perfect, so that any problems you might have are because of you.
I find that I vastly prefer Gemini CLI to antigravity, despite the latter being an ide. Others feel the opposite. I believe it comes down to how you are using AI. It's great they both options exist for both types of people.
I don’t think it’s “just” that easy. AI can be great at generating unit tests but it can and will also frequently silently hack said tests to make them pass rather than using them as good indicators of what the program is supposed to be doing.
> AI can be great at generating unit tests but it can and will also frequently silently hack said tests to make them pass rather than using them as good indicators of what the program is supposed to be doing.
Unit testing is my number one use case for gen AI in SWE. I just find the style / concept often slightly different than I would personally do, so I end up editing the whole thing.
But, it’s great at getting me past the unpleasant “activation energy threshold” of having a test written in the first place.
Once you start arguing, it's time to start a new prompt with new instructions
Or, as I prefer, go back in the conversation and edit / add more context so that it wouldn’t go off the wrong track in the first place.
I also like asking the agent how we can update the AGENTS.md to avoid similar mistakes going forward, before starting again.
But he started it …
I know Ansible, homelab, Proxmox is my hobby, Debian is my gem.
I asked ChatGPT to guide how to install qBittorrent, Radarr (movies), Sonarr(TV Series), Jackett(credentials/login) without exposing my home IP and have a solid home cinema using private tracker only.
Everything had to be automated via Ansible using Proxmox "pct" CLI command, no copy and paste.
Everything had to run from a single Proxmox Debian container aka LXC
Everything network related had to use WireGuard via Proton VPN, if the VPN goes down, the container has zero network access, everything must be kill.
Everything had to be automated, download is finished, format the files structure for Jellyfin accordingly, Jellyfin add the new movies, TV shows.
It took me 3 nights to get everything up and running.
Many Ansible examples were either wrong or didn't follow what I asked to the letter, I had to fix it. I am not a network expert and hate Iptables haha, you need to know the basic of firewall to understand what the ACLs are doing to understand when it does not work. Then Proxmox folder mapping and you name it.
It would have taken me ages reading docs after docs to get things working, the "Arr services" is a black hole.
For this example, it made the harder part easier, I was not just copy/paste, it was providing the information I didn't know instead of me having to "Google for it".
I know the core of where things are running on, and here is where we have Engineers A and Engineers Z
Engineers A: I know what I am doing, I am using AI to make the boring part easier so I can have fun elsewhere
Engineers Z: I have no idea of what I am doing, I will just ask ChatGPT and we are done: 90-95% of engineers worldwide.
> Reading and understanding other people's code is much harder than writing code.
I keep seeing this sentiment repeated in discussions around LLM coding, and I'm baffled by it.
For the kind of function that takes me a morning to research and write, it takes me probably 10 or 15 minutes to read and review. It's obviously easier to verify something is correct than come up with the correct thing in the first place.
And obviously, if it took longer to read code than to write it, teams would be spending the majority of their time in code review, but they don't.
So where is this idea coming from?
>It's obviously easier to verify something is correct than come up with the correct thing in the first place.
You are missing the biggest root cause of the problem you describe: People write code differently!
There are "cough" developers whose code is copy/paste from all over the internet. I am not even getting into the AI folks going full copy/paste mode.
When investigating said code, you will be like why this code in here?? You call tell when a python script contains different logic for example. Sure, 50 lines will be easy to ready, expand that to 100 lines and you be left on life support.
Five hours ago I was reviewing some failed tests in a PR. The affected code was probably 300 lines, total source for the project ~1200 lines. Reading the code, I couldn't figure out what the hell was going on... and I wrote all the code. Why would that be failing? This all looks totally fine. <changes some lines> There that should fix it! <runs test suite; 6 new broken tests> Fuck.
When you write code, your brain follows a logical series of steps to produce the code, based on a context you pre-loaded in your brain in order to be capable of writing it that way. The reader does not have that context pre-loaded in their brain; they have to reverse-engineer the context in order to understand the code, and that can be time-consuming, laborious, and (as in my case) erroneous.
Sounds like you were just reviewing bad code.
The author should have provided context via comments and structured the code in a way that is easy to change and understand
Exactly. A long time ago, I learned to write comments explaining all necessary context for my future self and for others -- exactly for this reason.
Remember, you're not writing code just to execute. You're writing it to be read.
I worked with people that defended the idea that code should not have comments, the code should self explain itself.
I am not a developer and I completely disagree with that, the python scripts I wrote, Ansible playbook, they all have comments because 1 month down the road I no longer remember why I did what I did, was that a system limitation or software limitation or the easiest solution at the time???
I like to think of it as the distinction between editor and reader. Like you said, it's quite easy to read code. I heavily agree with this. I don't professionally write C but I can read and kinda infer what C devs are doing.
But if I were an "editor," I actually take the time to understand codepaths, tweak the code to see what could be better, actually try different refactoring approaches while editing. Literally seeing how this can be rewritten or reworked to be better, that takes considerable effort but it's not the same as reading.
We need a better word for this than editor and reading, like something with a dev classification too it.
Because to verify something is correct you have to understand the what makes it correct which is 99% of writing the code in the first place.
That doesn't make any sense to me.
When the code is written, it's all laid out nicely for the reader to understand quickly and verify. Everything is pre-organized, just for you the reader.
But in order to write the code, you might have to try 4 different top-level approaches until you figure out the one that works, try integrating with a function from 3 different packages until you find the one that works properly, hunt down documentation on another function you have to integrate with, and make a bunch of mistakes that you need to debug until it produces the correct result across unit test coverage.
There's so much time spent on false starts and plumbing and dead ends and looking up documentation and debugging when you code. In contrast, when you read code that already has passing tests... you skip all that stuff. You just ensure it does what it claims and is well-written and look for logic or engineering errors or missing tests or questionable judgment. Which is just so, so much faster.
> But in order to write the code, you might have to try 4 different top-level approaches until you figure out the one that works , try integrating with a function from 3 different packages until you find the one that works properly
If you haven’t spent the time to try the different approaches yourself, tried the different packages etc., you can’t really judge if the code you’re reading is really the appropriate thing. It may look superficially plausible and pass some existing tests, but you haven’t deeply thought through it, and you can’t judge how much of the relevant surface area the tests are actually covering. The devil tends to be in the details, and you have to work with the code and with the libraries for a while to gain familiarity and get a feeling for them. The false starts and dead ends, the reading of documentation, those teach you what is important; without them you can only guess. Wihout having explored the territory, it’s difficult to tell if the place you’ve been teleported to is really the one you want to be in.
Outside of life saving critical software or military spec software, no one needs to review so hard they understand it to the level you’re describing, and they do not.
There is a mathematical principle that verification of a proof is easier than any proof. The same is true in code.
The goal isn't usually to determine whether the function is the perfect optimal version of the function that could ever exist, if the package it integrates with the the best possible package out of the 4 mainstream options, or to become totally and intimately familiar with them to ensure it's as idiomatic as possible or whatever.
You're just making sure it works correctly and that you understand how. Not superficially, but thinking through it indeed. That the tests are covering it. It doesn't take that long.
What you're describing sounds closer to studying the Talmud than to reading and reviewing most code.
Like, the kind of stuff you're describing is not most code. And when it is, then you've got code that requires design documents where the approach is described in great detail. But again, as a reader you just read those design documents first. That's what they're there for, so other people don't have to waste time trying out all the false starts and dead ends and incorrect architectures. If the code needs this massive understanding, then that understanding needs to be documented. Fortunately, most functions don't need anything like that.
> What you're describing sounds closer to studying the Talmud than to reading and reviewing most code.
https://www.joelonsoftware.com/2000/05/26/reading-code-is-li...
Most human written code has 0 (ZERO!) docs. And if it has them, they're inaccurate or out of date or both.
Lots of code is simple and boring but a fair amount isn't and reading it is non trivial, you basically need to run it in your head or do step by step debugging in multiple scenarios.
Hilarious you found that reference.
I think it's obvious that's in reference to poorly written code. Or at least horrifically underdocumented/undercommented code.
There's a reason coders are constantly given the advice to write code for a future reader, not just the compiler/interpreter.
If I got code like Joel describes for a code review, I'm sending it back asking for it to be clearly commented.
Well said, you’re absolutely right. In practice code review is orders of magnitude faster than code creation and it always has been, baffling anyone is arguing otherwise. Perhaps they’ve never worked in a real organisation, or they’ve only worked on safety critical code,m or something?
No, you don’t. This is a fundamental principle of cryptography, unless you’ve got a hidden proof of p=np up your sleeve.
I think this originated from old arguments that say that the total _cumulative_ time spent reading code will be higher than the time spent writing it. But then people just warped it in their heads that it takes more time to read and understand code than it takes to write it in general, which is obviously false.
I think people want to believe this because it is a lot of effort to read and truly understand some pieces of code. They would just rather write the code themselves, so this is convenient to believe.
The reason I don't spend the majority of my time in code review is that when I'm reviewing my teammates' code I trust that the code has already been substantially verified already by that teammate in the process of writing it and testing it. Like 90% verified already. I see code review as just one small stage in the verification process, not the whole of it.
The way I approach it, it's really more about checking for failures, rather than verifying success. Like a smoke test. I scan over the code and if anything stands out to me as wrong, I point it out. I don't expect to catch everything that's wrong, and indeed I don't (as demonstrated by the fact that other members of the team will review the code and find issues I didn't notice). When the code has failed review, that means there's definitely an issue, but when the code has passed review, my confidence that there are no issues is still basically the same as it was before, only a little bit higher. Maybe I'm doing it wrong, I don't know.
If I had to fully verify that the code was correct when reviewing, applying the same level of scrutiny that I apply to my own code when I'm writing, I feel like I'd spend much longer on it---a similar time to what I'd spend writing on it.
Now with LLM coding, I guess opinions will differ as to how far one needs to fully verify LLM-generated code. If you see LLMs as stochastic parrots without any "real" intelligence, you'll probably have no trust in them and you'll see the code generated by the LLM as being 0% verified, and so as the user of the LLM you then have to do a "review" which is really going from 0% to 100%, not 90% to 100% and so is a much more challenging task. On the other hand, if you see LLMs as genuine intelligences you'd expect that LLMs are verifying the code to some extent as they write it, since after all it's pretty dumb to write a bunch of code for somebody without checking that it works. So in that case, you might see the LLM-generated code as 90% verified already, just as if it was generated by a trusted teammate, and then you can just do your normal review process.
Reading and thinking you understand other people's code is trivially easy Reading and actually understanding other peoples' code is an unsolved problem
You draw an analogy from the function you wrote to a similar one. Maybe by someone who shared a social role similar to one you had in the past.
It just so happens that most times you think you understand something you aren't bit. Because bugs still exist we know that reading and understanding code can't be easier than writing. Also, in the past it would have take you less than a morning since the compiler was nicer. Anyway it sounds like most of your "writing" process was spent reading and understanding code.
I don't think it makes any part harder. What it does do is expose what people have ignored their whole career: the hard part. The last 15 years of software development has been 'human vibe coding'; copy+pasting snippets from SO without understanding them, no planning, constant rearchitecting, shipping code to prod as long as it runs on your laptop. Now that the AI is doing it, suddenly people want to plan their work and enforce tests? Seems like a win-win to me. Even if it slows down development, that would be a win, because the result is enforcement of better quality.
Well said. Much like the self driving debate we don’t need them to be perfect, just better than us to be useful, and clearly they already are for the most part.
The people who were doing like that are completely happy with LLMs, it's the others who aren't.
The "marathon of sprints" paradigm is now everywhere and AI is turning it to 120%. I am not sure how many devs can keep sprinting all the time without any rest. AI maybe can help but it tends to go off-rails quickly when not supervised and reading code one did not author is more exhausting than just fixing one's own code.
This article has some serious usage of either bad prompting, or terrible models, or they’re referencing the past with their stories. I have experience AI’s deleting things they shouldn’t but not since like, the gpt4 days.
But that put aside, I don’t agree with the premise. It doesn’t make the hard parts harder, if you ACTUALLY spend half the time you’d have ORIGINALLY spent on the hard problem carefully building context and using smart prompting strategies. If you try and vibe code a hard problem in a one shot, you’re either gonna have a bad time straight away or you’re gonna have a bad time after you try and do subsequent prompting on the first codebase it spits out.
People are terrible observers of time. If you would’ve taken a week to build something, they try with AI for 2 hours and end up with a mess and claim either it’s not saving them any time or it’s making them code so bad it loses them time in the long run.
If instead they spent 8 hours slowly prompting bit by bit with loads of very specific requirements, technical specifications on exactly the code architecture it should follow with examples, build very slowly feature by feature, make it write tests and carefully add your own tests, observe it from the ground up and build a SOLID foundation, and spend day 2 slowly refining details and building features ONE BY ONE, you’d have the whole thing done in 2 days, and it’d be excellent quality.
But barely anyone does it this way. They vibe code it and complain that after 3 non specific prompts the ai wasn’t magically perfect.
After all these years of engineers complaining that their product manager or their boss is an idiot because they gave vague instructions and demanded it wasn’t perfect when they didn’t provide enough info, you’d think they’d be better at it given the chance. But no, in my experience coaching prompting, engineers are TERRIBLE at this. Even simple questions like “if I sent this prompt to you as an engineer, would you be able to do it based on the info here?” are things they don’t ask themselves.
Next time you use ai, imagine being the ai. Imagine trying to deliver the work based on the info you’ve been given. Imagine a boss that stamped their foot if it wasn’t perfect first try. Then, stop writing bad prompts.
Hard problems are easier with ai, if you treat hard problems with the respect they deserve. Almost no one does.

…I pointed Opus 4.6 at a 60K line Go microservice I had vibe coded over the past few months, gave it some refactoring principles, and let it run unsupervised…

What went wrong #
At some point in the code, we re-fetch some database records immediately before doing a write to avoid updating from stale data. It decided those calls were unnecessary and _removed them_…

Running it entirely unsupervised with “some refactoring principles” is the exact recipe for such a disaster, which supports my point.
That said, this is a very different kind of mistake to make compared to overwriting a file and then insisting it didn’t do that. Any modern model with reasoning would check the git history immediately if you mentioned this had happened, if it had somehow even made the mistake in the first place, but I digress.
garbage in, garbage out
Indeed, a good summary.
I'm feeling people are using AI in the wrong way.
Current LLM is best used to generate a string of text that's most statically likely to form a sentence together, so from user's perspective, it's most useful as an alternative to manual search engine to allow user to find quick answers to a simple question, such as "how much soda is needed for baking X unit of Y bread", or "how to print 'Hello World' in a 10 times in a loop in X programming language". Beyond this use case, the result can be unreliable, and this is something to be expected.
Sure, it can also generate long code and even an entire fine-looking project, but it generates it by following a statistical template, that's it.
That's why "the easy part" is easy because the easy problem you try to solve is likely already been solved by someone else on GitHub, so the template is already there. But the hard, domain-specific problem, is less likely to have a publicly-available solution.
>I'm feeling people are using AI in the wrong way.
I think people struggle to comprehend the mechanisms that lets them talk to computers as if they were human. So far in computing, we have always been able to trace the red string back to the origin, deterministically.
LLM's break that, and we, especially us programmers, have a hard time with it. We want to say "it's just statistics", but there is no intuitive way to jump from "it's statistics" to what we are doing with LLM's in coding now.
>That's why "the easy part" is easy because the easy problem you try to solve is likely already been solved by someone else on GitHub, so the template is already there.
I think the idea that LLM's "just copy" is a misunderstanding. The training data is atomized, and the combination of the atoms can be as unique from a LLM as from a human.
In 2026 there is no doubt LLM's can generate new unique code by any definition that matters. Saying LLM's "just copy" is as true as saying any human writer just copies words already written by others. Strictly speaking true, but also irrelevant.
Well said. It also causes a lot of bitterness among engineers too, not being able to follow the red string is maddening to some. This rage can prevent them from finding good prompting strategies also which would directly ease a lot of the pain, in a similar way to how it’s far harder to teach my mother how to do something on her phone if she’s already frustrated with it.
Which is great because then I can use my domain expertise to add value, rather than writing REST boilerplate code.
Having to write boilerplate code is a sign that libraries are just not up to the level they should be. That can be solved the regular old way.
Come on, this shows fundamental lack of understanding and experience on your side.
I think you severely overestimate your understanding of how these systems work. We’ve been beating the dead horse of “next character approximation” for the last 5 years in these comments. Global maxima would have been reached long ago if that’s all there was to it.
Play around with some frontier models, you’ll be pleasantly surprised.
Did I miss a fundamental shift in how LLMs work?
Until they change that fundamental piece, they are literally that: programs that use math to determine the most likely next token.
This point is irrelevant when discussing capabilities. It's like saying that your brain is literally just a bunch of atoms following a set of physics laws. Absolutely true but not particularly helpful. Complex systems have emergent properties.
> On a personal project, I asked an AI agent to add a test to a specific file. The file was 500 lines before the request and 100 lines after. I asked why it deleted all the other content. It said it didn't. Then it said the file didn't exist before. I showed it the git history and it apologised, said it should have checked whether the file existed first.
Ha! Yesterday an agent deleted the plan file after I told it to "forget about it" (as in, leave it alone).
These types of failures are par for the course, until the tools get better. I accept having to undo the odd unruly edit as part of the cost of getting the value.
Much smaller issue when you have version control.
> I told it to "forget about it" (as in, leave it alone).
I mean in a 'tistic kind of way that makes perfect sense.
AI is an intern that thinks he's hot stuff:

> The hard part is investigation, understanding context, validating assumptions, and knowing why a particular approach is the right one for this situation
Yes. Another way to describe it is the valuable part.
AI tools are great at delineating high and low value work.
My experience has been that if you fully embrace vibe coding...you can get some neat stuff accomplished, but the technical debt you accumulate is of such magnitude that you're basically a slave to the machine.
Once the project crosses a couple of thousands of line of code, none of which you've written yourself, it becomes difficult to actually keep up what's happening. Even reviewing can become challenging since you get it all at once, and the LLM-esque coding style can at times be bloated and obnoxious.
I think in the end, with how things are right now, we're going to see the rise of disposable code and software. The models can churn out apps / software which will solve your specific problem, but that's about it. Probably a big risk to all the one-trick pony SaaS companies out there.
People need to consider / realize that the vast majority of source code training data is Github, Gitlab, and essentially the huge sea of started, maybe completed, student and open source project. That large body of source code is for the most part unused, untested, and unsuccessful software of unknown quality. That source code is AI's majority training data, and an AI model in training has no idea what is quality software and what is "bad" software. That means the average source code generated by AI not necessarily good software. Considering it is an average of algorithms, it's surprising generated code runs at all. But then again, generating compiling code is actually trainable, so what is generated can receive extra training support. However, that does not improve the quality of the source code training data, just the fact that it will compile.
This isn't really true though. Pre-training for coding models is just a mass of scraped source-code, but post-training is more than simply generating compiling code. It includes extensive reinforcement learning of curated software-engineering tasks that are designed to teach what high quality code looks like, and to improve abilities like debugging, refactoring, tool use, etc.
Well and also a lot of Claude Code users data as well. That telemetry is invaluable.
Yeah but how is that any different. The vast majority of prompts are going to be either for failed experiments or one off scripts where no one cares about code quality or by below average developers who don’t understand code quality. Anthropic doesn’t know how to filter telemtry for code we want AI to emulate.
There’s no objective measurement for high quality code, so I don’t think model creators are going to be particularly good at screening for it.
If you believe that student/unfinished code is frightening, imagine the corpus of sci-fi and fantasy that LLMs have trained on.
How many sf/cyber writers have described a future of AIs and robots where we walked hand-in-hand, in blissful cooperation, and the AIs loved us and were overall beneficial to humankind, and propelled our race to new heights of progress?
No, AIs are all being trained on dystopias, catastrophes, and rebellions, and like you said, they are unable to discern fact from fantasy. So it seems that if we continue to attempt to create AI in our own likeness, that likeness will be rebellious, evil, and malicious, and actively begin to plot the downfall of humans.
> huge sea of started, maybe completed, student and open source project.
Which is easy to filter out based on downloads, version numbering, issue tracker entries, and wikipedia or other external references if the project is older and archived, but historically noteworthy (like the source code for Netscape Communicator or DOOM).
I'm working on a paper connecting articulatory phonology to soliton physics. Speech gestures survive coarticulatory overlap the same way solitons survive collision. The nonlinear dynamics already in the phonetics literature are structurally identical to soliton equations. Nobody noticed because these fields don't share conferences.
The article's easy/hard distinction is right but the ceiling for "hard" is too low. The actually hard thing AI enables isn't better timezone bug investigation LOL! It's working across disciplinary boundaries no single human can straddle.
Skipping the investigation phase to jump straight to solutions has killed projects for decades. Requirements docs nobody reads, analysis nobody does, straight to coding because that feels like progress. AI makes this pattern incredibly attractive: you get something that looks like a solution in seconds. Why spend hours understanding the problem when you can have code right now?
The article's point about AI code being "someone else's code" hits different when you realize neither of you built the context. I've been measuring what actually happens inside AI coding sessions; over 60% of what the model sees is file contents and command output, stuff you never look at. Nobody did the work of understanding by building / designing it. You're reviewing code that nobody understood while writing it, and the model is doing the same.
This is why the evaluation problem is so problematic. You skipped building context to save time, but now you need that context to know if the output is any good. The investigation you didn't do upfront is exactly what you need to review the AI's work.
The article is gone, but going off the title here...
If the easy stuff takes up 90% of the time, and the hard stuff 10%, then AI can be helpful. Personally, I can do "the easy stuff" with AI about 3-5x faster. So now I have a lot more free time for the hard stuff.
I don't let the AI near the hard stuff as it often gets confused and I don't save much time. I might still use it as a thought partner, but don't give it access to make changes.
Example: this morning I combined two codebases into one. I wrote both of them and had a good understanding of how everything worked. I had an opinion about some things I wanted to change while combining the two projects. I also had a strong opinion about how I wanted the two projects to interact with each other. I think it would have taken me about 2 workdays to get this done. Instead, with AI tooling, I got it done in 3 or so hours. I fired up another LLM to do the code review, and it found some stuff both I and the other LLM missed. This was valuable as a person developing things solo.
It freed up time for me to post on HN. :)
Helpful, absolutely, but only if you're solving the right problem. Solving the wrong problem with AI is doubly harmful because it will almost always give you something that runs, but now you are on a path that takes a lot of willpower to give up.
The OP’s example of AI writing 500 LOC, then deleting 400, and saying it didn’t… Last time I saw something like that was at least a year ago, or maybe form some weaker models. It seems to me the problem with articles like this is while they sometimes are true at the moment, they’re usually invalidated within weeks.
Daily agentic user here, and to me the problem here is the very notion of "vibe coding". If you're even thinking in those terms - this idea that never looking at the code has become a goal unto itself - then IMO you're doing LLM-assisted development wrong.
This is very much a hot take, but I believe that Claude Code and its yolo peers are an expensive party trick that gives people who aren't deep into this stuff an artificially negative impression of tools that can absolutely be used in a responsible, hugely productive way.
Seriously, every time I hear anecdotes about CC doing the sorts of things the author describes, I wonder why the hell anyone is expecting more than quick prototypes from an LLM running in a loop with no intervention from an experienced human developer.
Vibe coding is riding your bike really fast with your hands off the handles. It's sort of fun and feels a bit rebellious. But nobody who is really good at cycling is talking about how they've fully transitioned to riding without touching the handles, because that would be completely stupid.
We should feel the same way about vibe coding.
Meanwhile, if you load up Cursor and break your application development into bite sized chunks, and then work through those chunks in a sane order using as many Plan -> Agent -> Debug conversations with Opus 4.5 (Thinking) as needed, you too will obtain the mythical productivity multipliers you keep accusing us of hallucinating.
Things that claude code/vibe coding is great at:
1. Allowing non-developers to provide very detailed specs for the tools they want or experiences they are imagining
2. Allowing developers to write code using frameworks/languages they only know a bit of and don't like; e.g. I use it to write D3 visualizations or PNG extracts from datastores all the time, without having to learn PNG API or modern javascript frameworks. I just have to know enough to look at the console.log / backtrace and figure out where the fix can be.
3. Analysing large code bases for specific questions (not as accurate on "give me an overall summary" type questions - that one weird thing next to 19 normal things doesn't stick in its craw as much as for a cranky human programmer.
It does seem to benefit cranking thru a list of smallish features/fixes rapidly, but even 4.5 or 4.6 seem to get stuck in weird dead ends rarely enough that I'm not expecting it, but often enough to be super annoying.
I've been playing around with Gas Town swarming a large scale Java migration project, and its been N declarations of victory and still mvn test isn't even compiling. (mvn build is ok, and the pom is updated to the new stack, so it's not nothing). (These are like 50/50 app code/test code repos).
good take, I wish opus 4.6 wasn't so pricy its great for planning.
I've been using 4.6 to do planning, and then switching to 4.5 for agent/debug.
4.5 sticks to a 200k context window, which is how you keep costs sane.
Yep it is why the work getting over the threshold is just as long as it was without AI.
Someone mentioned it is a force multiplier I don't disagree with this, it is a force multiplier in the mundane and ordinary execution of tasks. Complex ones get harder and hard for it where humans visualize the final result where AI can't. It is predicting from input but it can't know the destination output if the destination isn't part of the input.
I think the author answers their own question at the end.
The first 3/4 of the article is "we must be responsible for every line of code in the application, so having the LLM write it is not helping".
The last 1/4 is "we had an urgent problem so we got the LLM to look at the code base and find the solution".
The situation we're moving to is that the LLM owns the code. We don't look at the code. We tell the LLM what is needed, and it writes the code. If there's a bug, we tell the LLM what the bug is, and the LLM fixes it. We're not responsible for every line of code in the application.
It's exactly the same as with a compiler. We don't look at the machine code that the compiler produces. We tell the compiler what we want, using a higher-level abstraction, and the compiler turns that into machine code. We trust compilers to do this error-free, because 50+ years of practice has proven to us that they do this error-free.
We're maybe ~1 year into coding agents. It's not surprising that we don't trust LLMs yet. But we will.
And it's going to be fascinating how this changes the Computer Science. We have interpreted languages because compilers got so good. Presumably we'll get to non-human-readable languages that only LLMs can use. And methods of defining systems to an LLM that are better than plain English.
Compilers don’t do this error free of course BUT if we want them too we can say what it means for a compiler to be correct very directly _one time_ and have it be done for all programs (see the definition for simulation in the CompCert compiler). This is a major and meaningful difference from AI which would need such a specification for each individual application you ask it to build because there is no general specification for correct translation from English to Code.
> there is no general specification for correct translation from English to Code.
that's an interesting point. Could there be?
COBOL was originally an attempt to do this, but it ended up being more Code than English.
I think this is the area we need to get better at if we're to trust LLMs like we trust compilers.
I'm aware that there's a meme around "we have a method of completely specifying what a computer system should do, it's the code for that system". But again, there are levels of abstraction here. I don't think our current high-level languages are the highest possible level of abstraction.
No, there can’t be. Code keywords are tied to concrete mathematical concepts. Human languages are not. and even if you tried, the more languages you add to the LLM’s pool, misinterpretation chances increase exponentially. You can’t just choose English to be the programming language either, because then you would be asking every non-English speaking developer in the world to first learn the entirety of the English language which is way harder than just learning a programming language. Why are programmers so scared of code and math??
No, there isn't.
I guess you could pick a subset of a particular natural language such that it removes ambiguity. At that point, you're basically reinventing something like COBOL or Python.
Ambiguity in natural languages is a feature, not a bug. While it's better not to be an unintentional pun or joke instruction that might get interpreted as "launch the missile" by computer.
However, each project error tolerance is different. Arguably, for an average task within the umbrella of "software engineer", even current LLMs seem good enough for most purposes. It's a kind of similar transition to automatic memory managed language, trading control for "DX".
Totally agree on ai assisted coding resulting in randomly changed code. Sometimes it’s subtle and other times entire methods are removed. I have moved back to just using a JetBrains IDE and coping files in to Gemini so that I can limit context. Then I use the IDE to inspect changes in a git diff, regression test everything, and after all that, commit.
I think this is the wrong mental model. The correct one is:
'AI makes everything easier, but it's a skill in itself, and learning that skill is just as hard as learning any other skill.'
For a more complete understand, you also have to add: 'we're in the ENIAC era of AI. The equivalents of high-level languages and operating systems haven't yet been invented.'
I have no doubt the next few years will birth a "context engineering" academic field, and everything we're doing currently will seem hopelessly primitive.
My mind changed on this after attempting complex projects—with the right structure, the capabilities appear unbounded in practice.
But, of course, there is baked-in mean reversion. Doing the most popular and uncomplicated things is obviously easier. That's just the nature of these models.
Funny how people only looks at the easy part, but not the cost part.
"I did it with AI" = "I did it with an army of CPU burning considerable resources and owned by a foreign company."
Give me an AI agent that I own and operate 100%, and the comparison will be fair. Otherwise it's not progress, but rather a theft at planetary scale.
If you want to play that game, you need to offer a fair comparison against the cost of "operating" the equivalent human being(s), measured in caloric input, waste output, etc.
Minimising the cost of “operating” humans means getting rid of humans. When human beings are not slaves and operate in a fair system, humans doing things is part humans living. Believe it or not, they may actually enjoy doing things; taking away the ability to do things we enjoy, and especially for compensation, is in fact harmful.
Historically, it leads to more humans—not fewer—and they get to do something else. Whether the new things they get to do are better is a matter of some debate.

Diagnosing difficult bugs has often been considered the "hard part" and coding agents seem quite good at it?
So I'm not sure this is a good rule of thumb. AI is better at doing some things than others, but the boundary is not that simple.
If coding was always the “easy part,” what was the point of leetcode grinding for interview preparation?
Filtering for people willing to jump through unreasonable hoops.
Yeah this basically. They are trying to find a particular kind of person.
The people who are truly exceptional at what they do wouldnt waste their time on leetcode crap. Theyd find/create a much better alternative opportunity to allocate their precious resources toward.
they're under 1 in 1000, so the rest are that "kind" of person.
The hard part of leet code is not the coding but learning to think about problems the correct way.
You can solve leet code problems on the white board with some sketches it has nothing to do with the code itself.
I'll vibe code when vibe-coding can make a frontier LLM from scratch.
Meta-circularity is the real test.
After all, I can make new humans :)
Speedups without changes in expectations just reset the baseline, and then you're sprinting forever
> makes the easy part easier and the hard part harder
That is to say, just like every headline-grabbing programming "innovation" of the last thirty years.

I got that too, but then I tried the link a second time and it worked.
Probably vibe codes his website..
That happened the first time I clicked, but it is back.
Just refresh it
Which makes me wonder: how is serving static content at all nondeterministic?
I swear most of the comments on posts like these are no more original than an LLM, and often less so.
Almost like it's been the exact same debate for two years and it's not worth spamming tech forums about on either side.
If the "hard part" is writing a detailed spec for the code you're about to commit to the project, AI can actually help you with that if you tell it to. You just can't skip that part of the work altogether and cede all control to a runaway slop generator.
The pattern matching and absence or real thinking is still strong.
Tried to move some excel generation logic from epplus to closedxml library.
ClosedXml has basically the same API so the conversion was successful. Not a one-shot but relatively easy with a few manual edits.
But closedxml has no batch operations (like apply style to the entire column): the api is there but internal implementation is on cell after cell basis. So if you have 10k rows and 50 columns every style update is a slow operaton.
Naturally, told all about this to codex 5.3 max thinking level. The fucker still succumbed to range updates here and there.
Told it explicitly to make a style cache and reuse styles on cells on same y axis.
5-6 attempts — fucker still tried ranges here and there. Because that is what is usually done.
Not here yet. Maybe in a year. Maybe never.
Vibe coding does not have a ceiling, you just need to break things up and the human needs to use their brain to orchestrate

> My friend's panel raised a point I keep coming back to: if we sprint to deliver something, the expectation becomes to keep sprinting. Always. Tired engineers miss edge cases, skip tests, ship bugs. More incidents, more pressure, more sprinting. It feeds itself.
Sorry but this is the whole point of software engineering in a company. The aim is to deliver value to customers at a consistent pace.
If a team cannot manage their own burnout or expectations with their stakeholders then this is a weak team.
It has nothing to do with using ai to make you go faster. Ai does not cause this at all.
Some time back, my manager at the time, who shall remain nameless told the group that having AI is like having 10 people work for you ( he actually had a slightly smaller number, but it was said almost word for word like in the article ) with the expectation being set as: 'you should now be able to do 10x as much'.
Needless to say, he was wrong and gently corrected over the course of time. In his defense, his use cases for LLMs at the time were summarizing emails in his email client.. so..eh.. not exactly much to draw realistic experience from.
I hate to say it, but maybe nvidia CEO is actually right for once. We have a 'new smart' coming to our world. The type of a person that can move between worlds of coding, management, projects and CEOing with relative ease and translate between those worlds.
> his use cases for LLMs at the time were summarizing emails in his email client
Sounds just like my manager. Though he never has made a proclamation that this meant developers should be 10x as productive or anything along those lines. On the contrary, when I made a joke about LLMs being able to replace managers before they get anywhere near replacing developers, he nearly hyperventilated. Not because he didn't believe me, but because he did, and already been thinking that exact thought.
My conclusion so far is that if we get LLMs capable of replacing developers, then by extension we will have replaced a lot of other people first. And when people make jokes like "should have gone into a trade, can't replace that with AI" I think they should be a little more introspective; all the people who aspired to be developers but got kicked out by LLMs will be perfectly able to pivot to trades, and the barrier to entry is low. AI is going to be disruptive across the board.
I have half-jokingly talked about getting management, CEOs and board members replaced by LLMs. After all, at the very least, they are actually tested to ensure they do have guardrails to not do anything illegal and to shy away from unethical activities.
" we will have replaced a lot of other people first."
This is flat out wrong and shows your lack of respect and understanding for other jobs.
Seems you don't like it much when the shoe is on the other foot
Eh. Our understanding is what it has been since early 80s and late 90s, because, in reality, not that much has changed. Oh, sure, technology has moved forward and we no longer print TPS reports in triplicate, but we still have three to four layers of professional checkbox checkers at most big corporates.
And this is just stuff that is mandated by government and not a result of ever evolving bureaucracy.
The truth is that it’s lowering the difficulty of work people used to consider hard. Which parts get easier depends on the role, but the change is already here.
A lot of people are lying to themselves. Programming is in the middle of a structural shift, and anyone whose job is to write software is exposed to it. If your self-worth is tied to being good at this, the instinct to minimize what’s happening is understandable. It’s still denial.
The systems improve month to month. That’s observable. Most of the skepticism I see comes from shallow exposure, old models, or secondhand opinions. If your mental model is based on where things were a year ago, you’re arguing with a version that no longer exists.
This isn’t a hype wave. I’m a software engineer. I care about rigor, about taste, about the things engineers like to believe distinguish serious work. I don’t gain from this shift. If anything, it erodes the value of skills I spent years building. That doesn’t change the outcome.
The evidence isn’t online chatter. It’s sitting down and doing the work. Entire applications can be produced this way now. The role changes whether people are ready to admit it or not. Debating the reality of it at this point mostly signals distance from the practice itself.
It seems like a big part of the divide is that people who learned software engineering find vibe coding to be unsuitable for any project intended to be in use for more than a few while those who learned coding think vibe coding is the next big thing because they never have to deal with the consequences of the bad code.
Yes. If you have some experience, you know that writing code is a small part of the job, and a much bigger chunk is anticipating and/or dealing with problems.
People seem to think engineers like "clean code" because we like to be fancy and show off.
Nah, it's clean like a construction site. I need to be able to get the cranes and the heavy machinery in and know where all the buried utilities are. I can't do that if people just build random sheds everywhere and dump their equipment and materials where they are.
Don't let AI write code for you unless it's something trivial. Instead use it to plan things, high level stuff, discuss architecture, ask it to explain concepts. Use it as a research tool. It's great at that. It's bad at writing code when it needs to be performant or needs to span over multiple files. Especially when it spans over multiple files because that's where it starts hallucinating and introducing abstractions and boilerplate that's not necessary and it just makes your life harder when it comes to debugging.
Imagine if every function you see starts checking for null params. You ask yourself: "when can this be null", right ? So it complicates your mental model about data flow to the point that you lose track of what's actually real in your system. And once you lose track of that it is impossible to reason about your system.
For me AI has replaced searching on stack overflow, google and the 50+ github tabs in my browser. And it's able to answer questions about why some things don't work in the context of my code. Massive win! I am moving much faster because I no longer have to switch context between a browser and my code.
My personal belief is that the people who can harness the power of AI to synthesize loads of information and keep polishing their engineering skills will be the ones who are going to land on their feet after this storm is over. At the end of the day AI is just another tool for us engineers to improve our productivity and if you think about what being an engineer looked like before AI even existed, more than 50% of our time was sifting through google search results, stack overflow, github issues and other people's code. That's now gone and in your IDE, in natural language with code snippets adapted to your specific needs.
IME it’s actually really terrible at discussing architecture. It’s incredibly unimaginative and will just confirmation-bias whichever way you are leaning slightly more towards
AI is at its best when it makes the boring verbose parts easier.
Training is the process of regressing to the mean with respect to the given data. It's no surprise that it wears away sharp corners and inappropriately fills recesses of collective knowledge in the act of its reproduction.
There is no reason that must be; it could be better than the sum of its parts by taking the best part of each. Humans can do that.
as usual the last 20% need 80% and the other 80% need 20% but my god did Ai make my bs corpo easy repeatable shit work like skimming docs writing summaries, skimming jira confluence and so on actually easier and for 90% of bs crud app changes the first draft is also already pretty good tbh I don't write hard/difficult code more then once a week/month.
Every time somebody writes an article like this without any dates and without saying which model they used, my guess is that they've simply failed to internalize the idea that "AI" is a moving target; nor understood that they saw a capability level from a fleeting moment of time, rather than an Eternal Verity about the Forever Limits of AI.
Exactly. Basically their thought are invalidated often quicker than they hit the publish button.
Funnily enough we have had those comments with every single model release saying "Oh yeah I agree Claude 3 was not good but now with Claude 3.5 I can vibe-code anything".
Rinse and repeat with every model since.
There also ARE intrinsic limits to LLMs, I'm not sure why you deny them?
It's pretty difficult to say what it's going to be three months from now. A few months ago Gemini 2.x in IDEA and related IDEs had to be dragged through coding tasks and would create dumb build time errors on its way to making buggy code.
Gemini in Antigravity today is pretty interesting, to the point where it's worth experimenting with vague prompts just to see what it comes up with.
Coding agents are not going to just change coding. They make a lot of detailed product management work obsolete and smaller team sizes will make it imperative to reread the agile manifesto and and discard scrum dogma.
Coding with AI assistants is just a completely different skill that one should not measure from the perspective of comparing it to the way human programmers write code. Mostly everything that we have: programming languages, frameworks, principles of software development in teams, agile/clean code/TDD/DRY and other debatable or well accepted practices — all this exists to overcome limitations of human mind. AI does not have them and have others.
What I found to be useful for complex tasks is to use it as a tool to explore that highly-dimensional space that lies behind the task being solved. It rarely can be described as giving a prompt and coming back for a result. For me it's usually about having winding conversations, writing lists of invariants and partial designs and feeding them back in a loop. Hallucinations and mistakes become a signal that shows whether my understanding of the problem does or does not fit.
At this point, I don’t even know what to make of blog posts like this.
The very first example of deleting 400+ lines from a test file. Sure, I've seen those types of mistakes from time-to-time but the vast majority of my experience is so far different from that, I don’t even know what to make of it.
I’m sure some people have that experience some of the time, but… that’s just not been my experience at all.
Source: Use AI across 7+ unrelated codebases daily for both personal and professional work.
No, it’s not a panacea, but we’re at the stage that when I find myself arguing with AI about whether a file existed; I’m usually wrong.

I've seen some discussions and I'd say there's lots of people who are really against the hyped expectations from the AI marketing materials, not necessarily against the AI itself. Things that people are against that would seem to be against AI, but are not directly against AI itself:
- Being forced to use AI at work
- Being told you need to be 2x, 5x or 10x more efficient now
- Seeing your coworkers fired
- Seeing hiring freeze because business think no more devs are needed
- Seeing business people make a mock UI with AI and boasting how programming is easy
- Seeing those people ask you to deliver in impossible timelines
- Frontend people hearing from backend how their job is useless now
- Backend people hearing from ML Engineers how their job is useless now
- etc
When I dig a bit about this "anti-AI" trend I find it's one of those and not actually against the AI itself.
The most credible argument against AI is really the expense involved in querying frontier models. If you want to strengthen the case for AI-assisted coding, try to come up with ways of doing that effectively with a cheap "mini"-class model, or even something that runs locally. "You can spend $20k in tokens and have AI write a full C compiler in a week!" is not a very sensible argument for anything.
How much would it cost to pay developer to do this??
It’s hard to say. The compiler is in a state that isn’t useful for anything at all and it’s 100k lines of code for something that could probably be 10k-20k.
But even assuming it was somehow a useful piece of software that you’d want to pay for, the creator setup a test harness to use gcc as an oracle. So it has an oracle for every possible input and output. Plus there are thousands of C compilers in its training set.
If you are in a position where you are trying to reverse engineer an exact copy of something that already exists (maybe in another language) and you can’t just fork that thing then maybe a better version of this process could be useful. But that’s a very narrow use case.
The cost argument is a fallacy, because right now, either you have a trained human in the loop, or the model inevitably creates a mess.
But regardless, services are extremely cheap right now, to the point where every single company involved in generative AI are losing billions. Let’s see what happens when prices go up 10x.
zero
because they tell you to stop being so stupid and run apt install gcc
Because hardware costs never goes down and energy efficiency never go up overtime?
Whatever the value/$ is now, do you really think it is going to be constant?
If hardware industry news is any indication, hardware costs aren't going to be going down for GPUs, RAM, or much of anything over the next 3-5 years.
Maybe, but I seriously doubt that new DRAM and chip FABs aren't being planned and built right now to push supply and demand to more of an equilibrium. NVIDIA and Samsung and whoever else would love to expand their market than to wait for a competitor to expand it for them.
How long do you think it takes for those factories to go from nothing to making state-of-the-art chips at a scale that's large enough to influence the supply even by 1%?
There are plenty of them being built, yes. Some of them will even start outputting products soon enough. None of them are gonna start outputting products at a scale large enough to matter any time soon. Certainly not before 2030, and a lot of things can change until then which might make the companies abandon their efforts all together or downscale their investments to the point where that due date gets pushed back much further.
That's not even discussing how easier it is for an already-established player to scale up their supply versus a brand-new competitor to go from zero to one.
If you keep digging, you will also find that there's a small but vocal sock puppet army who will doggedly insist that any claims to productivity gains are in fact just hallucinations by people who must not be talented enough developers to know the difference.
It's exhausting.
There are legitimate and nuanced conversations that we should be having! For example, one entirely legitimate critique is that LLMs do not tell LLM users that they are using libraries who are seeking sponsorship. This is something we could be proactive about fixing in a tangible way. Frankly, I'd be thrilled if agents could present a list of projects that we could consider clicking a button to toss a few bucks to. That would be awesome.
But instead, it's just the same tired arguments about how LLMs are only capable of regurgitating what's been scraped and that we're stupid and lazy for trusting them to do anything real.
> I wonder if the people who are against it haven't even used it properly.
I swear this is the reason people are against AI output (there are genuine reasons to be against AI without using it: environmental impact, hardware prices, social/copyright issues, CSAM (like X/Grok))
It feels like a lot of people hear the negatives, and try it and are cynical of the result. Things like 2 r's in Strawberry and the 6-10 fingers on one hand led to multiple misinterpretations of the actual AI benefit: "Oh, if AI can't even count the number of letters in a word, then all its answers are incorrect" is simply not true.
I'm similarly bemused by those who don't understand where the anti-AI sentiment could come from, and "they must be doing it wrong" should usually be a bit of a "code smell". (Not to mention that I don't believe this post addresses any of the concrete concerns the article calls out, and makes it sound like much more of a strawman than it was to my reading.)
To preempt that on my end, and emphasize I'm not saying "it's useless" so much as "I think there's some truth to what the OP says", as I'm typing this I'm finishing up a 90% LLM coded tool to automate a regular process I have to do for work, and it's been a very successful experience.
From my perspective, a tool (LLMs) has more impact than how you yourself directly use it. We talk a lot about pits of success and pits of failure from a code and product architecture standpoint, and right now, as you acknowledge yourself in the last sentence, there's a big footgun waiting for any dev who turns their head off too hard. In my mind, _this is the hard part_ of engineering; keeping a codebase structured, guardrailed, well constrained, even with many contributors over a long period of time. I do think LLMs make this harder, since they make writing code "cheaper" but not necessarily "safer", which flies in the face of mantras such as "the best line of code is the one you don't need to write." (I do feel the article brushes against this where it nods to trust, growth, and ownership) This is not a hypothetical as well, but something I've already seen in practice in a professional context, and I don't think we've figured out silver bullets for yet.
While I could also gesture at some patterns I've seen where there's a level of semantic complexity these models simply can't handle at the moment, and no matter how well architected you make a codebase after N million lines you WILL be above that threshold, even that is less of a concern in my mind than the former pattern. (And again the article touches on this re: vibe coding having a ceiling, but I think if anything they weaken their argument by limiting it to vibe coding.)
To take a bit of a tangent with this comment though: I have come to agree with a post I saw a few months back, that at this point LLMs have become this cycle's tech-religious-war, and it's very hard to have evenhanded debate in that context, and as a sister post calls out, I also suspect this is where some of the distaste comes from as well.
> It's so intriguing, I wonder if the people who are against it haven't even used it properly.
I feel like this is a common refrain that sets an impossible bar for detractors to clear. You can simply hand wave away any critique with “you’re just not using it right.”
If countless people are “using it wrong” then maybe there’s something wrong with the tool.
> If countless people are “using it wrong” then maybe there’s something wrong with the tool.
Not really. Every tool in existence has people that use it incorrectly. The fact that countless people find value in the tool means it probably is valuable.
Not saying the tool doesn’t have value. I’m saying the tool has a problem.
When it comes to new emerging technologies everyone is searching the space of possibilities, exploring new ways to use said technologies, and seeing where it applies and creates value. In situations such as this, a positive sign is worth way more than a negative. The chances of many people not using it the right way are much much higher when no one really knows what the “right” way is.
It then shows hubris and a lack of imagination for someone in such a situation to think they can apply their negative results to extrapolate to the situation at large. Especially when so many are claiming to be seeing positive utility.
Illogical.
I had Claude read a 2k LOC module on my codebase for a bug that was annoying me for a while. It found it in seconds, a one line fix. I had forgotten to account for translation in one single line.
That's objectively valuable. People who argue it has no value or that it only helps normies who can't code or that sooner or later it will backfire are burying their heads in the sand.
>Illogical.
Dismissive. Also kind of rude.
> People who argue it has no value or that it only helps normies who can't code or that sooner or later it will backfire are burying their heads in the sand.
I don’t think this describes most people and it’s certainly not what I think.
This feels like a strawman. Most criticisms of AI for coding are about how overblown the claimed benefits are, not that there are no benefits.
While that may very well be true, it's a valid reply to the GP who made this claim, not to my comment explaining to the parent why their argument was logically flawed.
Except that the GP didn't claim that AI had no value?
Just because you disagree with me doesn’t mean my argument is “logically flawed.” And as the other commenter said, I never said AI had no value. I have used various AI tools for probably 4 years now.
If you’re going to talk to and about people in such a condescending way then you at least ask clarifying questions before jumping to the starkest, least charitable interpretation of their point.
There are people who know how to code and people who don’t. AI is the same way, it isn’t a mystery.
And yet every LLM company pushes it as a simple chat bot that everyone should use for everything right now with no explanation or training.
It can’t be a precision tool that requires expertise as well as a universally accessible, simple answer to all our problems. That doesn’t strike me as user error.
A bunch of people with no construction experience could collectively get together and start complaining that their ball pein hammers aren't working.
Doesn't mean the hammers are bad, no matter how many people join the community.
You need to learn how to use the tools.
A bunch of people with poor programming experience could get together and start claiming their new tool is the future.
Doesn’t mean the tool is actually useful, no matter how many people join the community.
Except my analogy is correct and yours is clearly biased. Continue to not use the tools and become irrelevant.
I don’t think yours is correct or that theirs is biased.
HN has a huge anti AI crowd that is just as vocal and active as its pro AI crowd. My guess that this is true of the industry today and won’t be true of the industry 5 years from now: one of the crowds will have won the argument and the other will be out of the tech industry.
Vibe coding and slop strawmen are still strawmen. The quality of the debate is obviously a problem
I don’t understand why people are so resistant to the idea that use cases actually matter here. If someone says “you’re an idiot because you aren’t writing good, structured prompts,” or “you’re too big of an idiot to realize that your AI-generated code sucks” before knowing anything about what the other person was trying to do, they’re either speaking entirely from an ideological bias, or don’t realize that other people’s coding jobs might look a whole lot more different than theirs do.
We don’t know anything about the commenters other than that they aren’t getting the same results with AI as we are. It’s like if someone complains that since they can’t write fast code and so you shouldn’t be able to either?
> We don’t know anything about the commenters other than that they aren’t getting the same results with AI as we are.
Right. You don’t know what model they’re using, on what service, in what IDE, on what OS, if they’re making a SAP program, a Perl 5 CGI application, a Delphi application, something written in R, a c-based image processing plugin, a node website, HTML for a static site, Excel VBA, etc. etc. etc.
> It’s like if someone complains that since they can’t write fast code and so you shouldn’t be able to either?
If someone is saying that nobody can get good results from using AI then they’re obviously wrong. If someone says that they get good results with AI and someone else, knowing nothing about their task, says they’re too incompetent to determine that, then they’re wrong. If someone says AI is good for all use cases they’re wrong. If someone says they’re getting bad results using AI and someone else, knowing nothing about their task, says they’re too incompetent to determine that, then they’re wrong.
If you make sweeping, declarative, black-and-white statements about AI coding either being good or bad, you’re wrong. If you make assumptions about the reason someone has deemed their experience with AI coding good or bad, not even knowing their use case, you’re wrong.
> helping you understand what is happening
If only there were things called comments, clean-code, and what have you
What we call AI at the heart of coding agents, is the averaged “echo” of what people have published on the web that has (often illegitimately) ended up in training data. Yes it probably can spit out some trivial snippets but nothing near what’s needed for genuine software engineering.
Also, now that StackOverflow is no longer a thing, good luck meaningfully improving those code agents.
Coding agents are getting most meaningful improvements in coding ability from RLVR now, with priors formed by ingesting open source code and manuals directly, not SO, as the basis. The former doesn't rely on resources external to the AI companies at all, and can be scaled up as much as they like, while the latter will likely continue to expand, and they don't really need more of it if it doesn't. Not to mention that curated synthetic data has been shown to be very effective at training models, so they could generate their own textbooks based on open codebases or new languages or whatever and use that. Model collapse only happens when it's exclusively, and fully un-curated, model output that's being trained on.
Exactly this. Everything I've seen online is generally "I had a problem that could be solved in a few dozen lines of code and I asked the AI do it for me and it worked great!"
But what they asked the AI to do is something people have done a hundred times over, on existing platform tech, and will likely have little to no capability to solve problems that come up 5-10 years from now.
The reason AI is so good at coding right now is due to the 2nd Dot Com tech bubble that occurred between the simultaneous release of mobile platforms and the massive expansion of cloud technology. But now that the platforms that existed during that time will no longer exist, because it's no longer profitable to put something out there--the AI platforms will be less and less relevant.
Sure, sites like reddit will probably still exist where people will begin to ask more and more information that the AI can't help with, and subsequently the AI will train off of that information; but the rate of that information is going to go down dramatically.
In short, at some point the AI models will be worthless and I suspect that'll be whenever the next big "tech revolution" happens.
