> I feel like people don't care whether you used an AI to write your code as long as it works

Oh, some do; for sure they do. Some put a "no ai" badge on their sites; others add disclaimers to their repos if ai has been used to write the code. But I agree with you about the productivity/output. Developers who refrain from using AI are probably more interested in the very process of coding than in its output. They pride themselves on their craft and craftsmanship.
