And, yes, I'm aware that most compilers are not entirely deterministic either, but LLMs are inherently nondeterministic. And I'm also aware that you can tweak LLMs to be more deterministic, but in practice they're never deployed like that.
Besides, creating software via natural language is an entirely different exercise than using a structured language purposely built for that.
We're talking about two entirely different ways of creating software, and any comparison between them is completely absurd.
