> Every mechanic works differently, because they have different bodies and minds.

Yes but the same LLM works very differently on each request. Even ignoring non-determinism, extremely minor differences in wording that a human mechanic wouldn’t even notice will lead to wildly different answers.

> LLMs are, of course, bad. Or not good enough, at least. But suppose they are. Suppose they're perfect.

You’re just talking about magic at that point.

But suppose the do become “perfect”, I’m skeptical we’ll ever have the compute resources to replace a significant fraction of computation with LLMs.
