@doug On the other side of this, if someone set up an Etsy store selling prints of AI art that used prompts like "Painting by [living artist]", and were deliberately emulating that artist or artists for the purpose of profiting off of their reputation, I would absolutely call that an infringement. That would be deeply unethical.
I think that there is some nuance to be afforded here.
Personally, I hope to see artist names removed from AI data sets so that their styles cannot be directly copied.
