Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.
This is not debate club. Unless it’s amusing debate.

i've collided with an article* https://harshanu.space/en/tech/ccc-vs-gcc/
you might be wondering why it doesn't highlight that it fails to compile linux kernel, or why it states that using pieces of gcc where vibecc fails is "fair", or why it neglects to say that failing linker means it's not useful in any way, or why just relying on "no errors" isn't enough when it's already known that vibecc will happily eat invalid c. it's explained by:
even with all this slant, by their own vibecoded benchmark, vibecc is still complete dogshit with sqlite compiled with it being slower up to 150000x times in some cases
Every single one of these failures is waved away because supposedly it's impressive that the AI can do this at all. Do they not realize the obvious problem with this argument? The AI has been trained on all the source code that Anthropic could get their grubby hands on! This includes GCC and clang and everything remotely resembling a C compiler! If I took every C compiler in existence, shoved them in a blender, and spent $20k on electricity blending them until the resulting slurry passed my test cases, should I be surprised or impressed that I got a shitty C compiler? If an actual person wrote this code, they would be justifiably mocked (or they're a student trying to learn by doing, and LLMs do not learn by doing). But AI gets a free pass because it's impressive that the slop can come in larger quantities now, I guess. These Models Will Improve. These Issues Will Get Fixed.
Ye, the former can be done in a month of non-full-time work by an undergrad who took Compilers 101 this semester or in literally a single day by a professional, and the latter is an actual useful product.
So of course AI will excel at doing the first one worse (vibecc doesn't even reject invalid C) and at an insane resource cost.
They would probably be even more impressed that you only spent $20k
