Why would companies accept AI generated code, it they can generate their own (and review the prompt)?

It's like predicting that when compilers become more popular, accepting binary contributions will become the default.

LLMs are non-deterministic, and compilers are (mostly) deterministic.

A good PR with AI is a like a series of dice rolls that you need to get right to get high-quality output. Folks asking for prompts are basically saying "hand me the dice, I'll do all the dice rolls." To which my response is "Why?"
