It's all about competition. Musicians dislike AI music because they're being outcompeted by AI. Same with artists. And, ironically, same with programmers.
AI programming isn't going to improve the state of the craft. Developers hate AI coding tools for the same reason they hated Dreamweaver back in the 00s: the generated code was crap. You'd spend more time "fixing" the generated code than you'd spend writing it from scratch.
What it is going to do is finally kill this obsession the tech industry has with moving fast and breaking things. We can't compete with AI on speed and breaking things. It's just not humanly possible. It's going to force the entire industry to find other metrics to compete on. I hope that's going to be quality (performance, uptime, and reliability), but, then again, I'm an optimist in this regard.
It's the same with music and art, too. AI isn't going to replace musicians and artists, but it is going to make them compete on different metrics than they're used to.
