I suspect we may have different definitions of what constitutes an "artist". I include digital art in my definition, and your statement above definitely isn't true for that. Are you just talking about painters/sketchers/etc who are doing it by hand?
If so, limiting the definition to that doesn't make a lot of sense to me, especially given that AI isn't replacing those gigs. If somebody already creates analog art, I don't see AI as being that much of a change for them
I even have rights over that pervious paragraph. It aint worth much but if someone wanted to monitize it i would have rights i could assert.
