The vast majority of artists in all fields don't really have their own style and are just copying other people's. Doesn't matter whether we're talking about art, literature, music, film, whatever.

It takes a rare genius to make a new style, and they come along a few times a generation. And even they will often admit they built on top of existing styles and other artists.

I'm not a fan of AI work or anything, but we need to be honest about what human 'creativity' usually is, which for most artists is basically copying the trends of the time with at most a minor twist.

OTOH, I think when you start entering the fringes of AI work you really start seeing how much it's just stealing other people's work though. With more niche subjects, it will often produce copies of the few artists in that field with a few minor, often bad, changes.
