<p>Extremely silly. Even if LLMs did everything that everyone says they do (which they absolutely don't), they still hit a fundamental limit of complexity when they stop being useful<p>Its only a good idea if you work in selling tokens, otherwise you're dooming anything other than a simple app to inevitably breaking after it hits a certain level of complexity</p>

<p>>I think it would be reasonable to ask which major open source projects aren't using AI assistance?<p>Where are all the vast quantity of LLM commits for these open source projects, if these engineers are truly 10xing their productivity with LLM code generation? Because I regularly browse the source of many of these, and can find almost no evidence that LLM code generation is anywhere near the level of productivity being claimed for:<p>1. ImGui<p>2. SFML<p>3. SDL<p>4. GLFW<p>5. OpenSSL<p>6. Linux<p>7. GCC<p>8. Clang/LLVM<p>9. Libc++/libstdc++/msstl<p>10. Rust<p>11. Godot<p>12. Nlohmann<p>13. Boost<p>14. Python<p>15. GNU tools<p>Etc etc. There are even more major projects, but these are just the critical ones I can think of off the top of my head. If you go for a browse though eg Godot, you might think that LLMs don't exist. In fact if you go for a browse through any of these, you might think that LLMs are borderline never used for code generation in the open source world. This is a diverse collection of random projects, and yet for some reason <i>none</i> of these have experienced a 10x increase in productivity in any form from any contributors from LLM code generation<p>>That is not why. Or at least not the majority of it<p>Its not the quantity, if maintainers were receiving incredibly high quality PRs that could just be merged, they'd be very happy. Godot is an example of a project that was initially pro LLM, and then had to about face because the PRs were just absolutely crap<p>>Some might be trash, some might be gold<p>Is there any evidence that any of these PRs have ever been gold?</p>

<p>How is it challenging for open source projects? You just write a PR, and try to get it to meet the maintainer's quality bar. That's exactly how all code is written in <i>any</i> environment - you do code review and refine a PR until its good enough to be merged</p>

<p>If they were sneaking LLM generated code into these projects, we'd expect to see their feature development 10x even if they covertly aren't telling anyone. Which open source codebases have seen a truly massive 10x increase in delivered feature velocity since AI turned up? Where are all the new contributors who contribute features at 10x the rate of the existing meatcoding developers?<p>Then all it'd take is <i>one</i> of these engineers blowing the lid on their whole secret LLM contribution strategy to absolutely break the industry wide open to the benefits of these massive productivity increases, and finally prove all the doubters wrong. They sure are good at keeping secrets that would directly benefit them to expose</p>

<p>You'd think <i>one</i> 10x engineer or one core developer already part of the project would have completely eclipsed all the other engineers, and worked around the difficulties there<p>Or, failing that, you'd think any of these engineers - given the truly vast amount of programming power now available at their fingertips with their 10x productivity - would have simply replaced these projects. It'd only take a few 10xers who wanted to show that everyone else was wrong. That's how open source often works, someone just gets a been in their bonnet and then we get linux<p>Instead: I can't find any of it. There's no evidence of this productivity boost in the wild. There aren't new high quality 10x open source projects springing up that are replacing everything. There aren't high quality LLM contributions, feature development isn't going faster. There's almost no evidence of high quality AI code generation at all in the open source space, existing projects or otherwise<p>Where's all the code? I want the receipts if people are claiming a 10x productivity. Because at the moment, the <i>much</i> more likely explanation seems to be that its simply not true</p>

<p>They don't though, very few people were anti AI in the early days. Open source projects were largely initially very interested in LLM usage, and generally had a pro AI contribution policy. This changed when it did not help their lives<p>Eg if you check out Godot, initially they were cool with LLM code, and then had to clamp down on it because it was not leading to anything good</p>

<p>The the idea that engineers are covertly sneaking huge quantities of LLM generated code into these projects doesn't pass the smell test, as there's lots of evidence that this isn't true. It'd be incredibly obvious if new contributors were turning up en masse and contributing absolutely incredible amounts of high quality code, because everyone would be crowing about it<p>Instead, if you check out something like ImGui, we can see that its largely just Omar as usual with a bunch of PRs. Nothing much seems to have changed, feature development carries on at the same pace as it did previously. This is replicated across nearly every single major long term open source project I can find<p>The only reason developers now feel the need to hide their LLM usage is because the LLM contributions have all been shockingly bad, so you're reversing cause and effect. If LLM contributions had been incredible, they wouldn't be frowned upon socially now. Surely someone would blow the lid on this huge covert conspiracy about how incredible their contributions to.. SFML have been?<p>This effect also wouldn't prevent LLMgineers from creating their own open source projects that should be absolutely <i>outstripping</i> the existing open source space. After all how old is ImGui? With a 10x productivity gain, it should take a year of development to easily match its features if those gains are truly real now<p>>if they're really good and use LLMs responsibly, they probably don't even have any ethical obligation to label LLM involvement<p>The copyright issues means that non disclosure is inherently unethical</p>

<p>Its always been possible to trade long term productivity for short term gains with technical debt. This is why the bar I'm interested in is long term projects, which have proven to have long term success, instead of a small disposable project where the code quality doesn't matter</p>

<p>Sure, it just seems a little odd that no LLMgineer ever contributes their incredible more performant scheduler back though right? After all if you can do it with claude, anyone can, all it'd take is to ask claude to rewrite it. Linux accepts LLM generated PRs, all the code has to do is meet the review bar and one of the most critical pieces of software engineering on the planet gets better for everyone</p>

<p>If that were true, we'd expect to see massively accelerated velocity of open source projects by these engineers. They should be creating new open source projects at a truly astounding rate, with new tooling springing up every day that dwarfs the existing open source space as their productivity completely eclipses traditional development<p>Instead, software is plodding along exactly the same as it did prior to LLM code generation, and there's no evidence of superprogrammers making superprojects in 1/10th of the time. With a 10x productivity gain, what used to take a year should take a month</p>

<p>Why would the PR format be bad for LLMs? Its just code review + merging in branches, which is what every company should be doing anyway<p>Nothing's stopping core developers from adopting LLM generated code for themselves, while banning it for external contributors</p>

<p>I recently asked it a series of technical physics questions about a field I used to be involved in to evaluate whether it'd be useful for doing research, and literally every single answer it gave was critically wrong - even for basic questions.

<p>>If agentic development actually worked the way any of them say it does<p>I think its fascinating just how much of a gap there is between what's being claimed, and the verifiable observable data of the open source world. Major open source projects are by and large starting to ban LLMs now, because the contributions made by LLM users have been universally terrible and unhelpful. There doesn't appear to be a single major project that's found generating code to lead to major productivity speedups, and the consensus appears to be that its just lead to a lot of crappy contributions that are harder to spot immediately as being obvious crap<p>I regularly see people claim that they are now 10x more productive with LLM code generation, and I just wonder where all the code is. Is it somehow true that these gains are only being realised in proprietary projects, and not a single one of them has put even a small fraction of their new found engineering powers into eg Godot? Why do only the poor quality LLM code generation users make PRs to open source projects, and never the engineers that know how to really use it correctly?<p>If you look in the open source major project space, you can find almost no evidence that AI code generation exists at all. Go browse your favourite critical tool and look for AI generated PRs that have landed in the codebase, its probably a <i>tiny</i> handful of them in comparison to the human written PRs prior to an LLM ban. It turns out that once you have a verifiable, open quality review bar, for some reason almost no LLM commits really meet the level of quality necessary<p>I strongly suspect that what we're seeing is that much of the tech code-writing economy had already become completely performative prior to AI turning up. It no longer matters in the current age if your code is good, or works, because your job is to give the illusion of product development while the stock market price gets pumped, until you all cash out your share value, get bought, or hop jobs in 2 years. For many companies it literally does not matter if you produce anything that generates value (or works), because the illusion of progress is all that matters. AI is absolutely incredible at creating the illusion of progress, because it looks a whole lot like real code, it just appears to have failed the bar of making actual projects that <i>work</i>. If that was never the goal in the first place, it probably really is a 10x productivity boost</p>

<p>I don't think there's a way to make it secure while still permitting it unprompted external access<p>Eg: Any web request is a security vulnerability, there's no way to do it if the web requests are being made maliciously<p>Say that we have an agent with access to get requests, solely to a single site <a href="https://yoursite.com" rel="nofollow">https://yoursite.com</a> without subdomains. In this case multiple requests can be sent, and the time between requests can be used to exfiltrate personal data, similar to the coffee shop attack but without the subdomains. If the AI is able to make requests in any form, some information can be leaked, where the amount of leakable information is tied to information theory content of whatever side channel is being used. The only 0 information channel is.. never to make a request<p>You could also completely trust the 3rd party you're connecting to, but that to me seems like a hard error in the modern internet</p>

<p>>So why are you pretending this is something new or novel?<p>Because as the OP of this thread and LLM users are rediscovering, that understanding is the most critical part of software development<p>>I don't think this personal opinion holds well when contrasted with reality. The truth of the matter is that in moderately large codebases, which is the norm in any production setting, at best you have a T-shape understanding of the system: in specific areas you might have somewhat deep understanding, but for the vast majority of the system you have at best a high level understanding of the software architecture.<p>I suspect a lot of people haven't worked on a system with engineers who've been there for 20 years working on it. There's simply no substitute for that kind of deep institutional knowledge, and it'll take you 5-10 years to be as productive as them simply because of that level of extreme knowledge about a codebase. It isn't as sexy as swapping jobs every 2 years though, so you have to go outside of the big tech bubble</p>

<p>Its weird how absolutely desperate we are to avoid humans actually using their brains at any step of the coding process. I don't know if we just need to tell people that its fine to need to think about things, and that its actively healthy to do so. Learning is good for you, and no chatgpt isn't good enough to avoid using your meat<p>If you don't engage your brain, it'll rot. That's far more important in the long term than a 5% productivity boost or something. I have no idea why you'd trade off your entire technical development and skillset training, for the most short term gains, it doesn't even theoretically make sense if you care about long term productivity</p>
