I mean, I share some of the concerns you expressed, but at the same time there is no chance at all that working programmers and artists won't be using LLMs (and whatever "AI" comes next).

I'm a programmer, and I enjoyed the sort of "craftsman" aspect of writing code, from the 1990s until... maybe last year. But it's over. Writing code manually is already the exception, not the rule. I am not an artist, and I also really do understand that artists have a more legitimate grievance (about stealing prior art) than we programmers do.

As a practical matter, though, that's irrelevant. I suspect being an "artist" working in games, movies, ads, etc will become much like coding already is: you produce some great work manually, as an example, and then tell the bots "Now do it like this ... all 100 of you."
