For the few times I've used both models side by side on more typical tasks (not so much web stuff, which I don't do much of, but more conventional Python scripts, CLI utilities in C, some OpenGL), they seem much more evenly matched. I haven't found a case where Claude would be markedly superior since Codex 5.2 came out, but I'm sure there are plenty. In my view, benchmarks are completely irrelevant at this point, just use models side by side on representative bits of your real work and stick with what works best for you. My software engineer friends often react with disbelief when I say I much prefer Codex, but in my experience it is not a close comparison.

Personally, I don't feel any moral obligation to investigate the personal views of people who write the software I use. Using software, especially free software, doesn't constitute an endorsement of the authors' views. Before this thread, I was blissfully unaware of this entire silly controversy, since Omarchy doesn't mention any politics anywhere as far as I can tell. If that ever changes, I'll delete it in a heartbeat (regardless of the kind of politics it happens to be), but so far the only people politicizing the issue seem to be its detractors.

I agree with everything else you said, but as someone who has used both OpenCL and Vulkan, the complexity is not comparable in the slightest. Even for pure compute applications, Vulkan is radically more annoying to use than OpenCL, though of course both are much worse than CUDA (or even Metal). OpenCL is somewhat annoying, but usable if you're okay with a basic C API, whereas Vulkan feels like an insufferable waste of time.

AFAIK, the only solution that actually works on all major platforms without additional compatibility layers today is OpenCL 1.2 - which also happens to be officially deprecated on MacOS, but still works for now.

In my experience, if you don't try to be excessively clever and just write straightforward C code, these issues almost never arise. Instead of wasting my time on the standard, I'd rather spend it validating the compilers I support and making sure my code works in the real world, not the one inhabited by the abstract machine of ISO C.

In reality, if you're writing C in 2025, you have a finite set of specific target platforms and a finite set of compilers you care about. Those are what matter. Whether my code is robust with respect to some 80s hardware that did weird things with integers, I have no idea and really couldn't care less.

I am one of those. I grok abstractions just fine (have commercially written idiomatically obtuse Scala and C#, some Haskell for fun, etc.), but I don't enjoy them.

I use them, of course (writing everything in raw asm is unproductive for most tasks), but rather than getting that warm fuzzy feeling most programmers seem to get when they finish writing a fancy clever abstraction and it works on the first try, I get it when I look at a piece of code I've written and realize there is nothing extraneous to take away, that it is efficient and readable in the sense of being explicit and clear, rather than hiding all the complexity away in order to look pretty or maximize more abstract concerns (reusability, DRY, etc.).

This mindset is a very good fit for writing compute-heavy numerical code, GPU stuff and lots of systems level code, not so much for being a cog in a large team on enterprise web backends, so I mostly write numerical code for physics simulations. You can write many other things this way and get very fast and bloatfree websites or anything else, but it doesn't work well in large teams or people using "industry best practices". It also makes me prefer C to Rust.

I've written very little Rust myself, but when I've tried, I've always come away with a similar impression that it's just not a good fit for performant numerical computing, with seemingly basic things (like proper SIMD support, const generics without weird restrictions, etc.) considered afterthoughts. For those more up to speed on Rust development, is this impression accurate, or have I missed something and should reconsider my view?
