They really are though. There seems to be some confusion about "determinism" as if everyone writes perfect code and every compiler interprets that code perfectly. There's bugs and nondeterminism in every step of the chain with human coders and, say, a .NET compiler too. The idea that we've got coding down to a pristine and exact science and AI is some random chaos element that muddies it makes no sense to me after seeing how most human created code works.
When it comes to non-determinism, the occasional bug or optimization difference in a compiler is not even in the same category as the 50+% chance of a different answer every time that you get with llms.
What programmer codes exactly the way of any other programmer? Human ability to write code is dependent on time allowed, how hungry they are, how much sleep they got and a million other non-determined factors.
