I guess writing code is now like creating punch-cards for old computers. Or even more recently, as writing ASM instead of using a higher level language like C. Now we simply write our "code" in a higher language, natural language, and the LLM is the compiler.

No we don't and we never should actually, compilers need to be deterministic.

It needs to be something stronger than just deterministic.

With the right settings, a LLM is deterministic. But even then, small variations in input can cause very unforeseen changes in output, sometimes drastic, sometimes minor. Knowing that I'm likely misusing the vocabulary, I would go with saying that this counts as the output being chaotic so we need compilers to be non-chaotic (and deterministic, I think you might be able to have something that is non-deterministic and non-chaotic). I'm not sure that a non-chaotic LLM could ever exist.

(Thinking on it a bit more, there are some esoteric languages that might be chaotic, so this might be more difficult to pin down than I thought.)

Why?

Also, give the same programming task to 2 devs and you end up with 2 different solutions. Heck, have the same dev do the same thing twice and you will have 2 different ones.

Determinism seems like this big gotcha, but in it self, is it really?

"Do the same thing" I need to be pedantic here because if they do the same thing, the exact same solution will be produced.

The compiler needs to guarantee that across multiple systems. How would QA know they're testing the version that is staged to be pushed to prod if you can't guarantee it's the same ?

This is not what a compiler is in any sense.

I cringe every time I read this "punch card" narrative. We are not at this stage at all. You are comparing deterministic stuff and LLMs which are not deterministic and may or may not give you what you want. In fact I personally barely use autonomous Agents in my brownfield codebase because they generate so much unmaintainable slop.

Except that compiler is a non-deterministic pull of a slot-machine handle. No thanks, I'll keep my programming skills; COBOL programmers command a huge salary in 2026, soon all competent programmers will.
