Your perspective is quite thoughtful, thank you. I do agree that if you are just fixing a bug or updating function internals, +20/-20 is certainty good enough and I wouldn’t oppose AI used there.

I am going to have to agree to disagree overall though, because the second there is something the AI can’t do the maintenance time for a human to learn the context and solve the problem skyrockets (in practice, for me) in a way I find unacceptable. And I may be wrong, but I don’t see LLMs being able to improve to close that gap soon because that would require a fundamental shift away from what the LLMs are under the hood.
