> fully replace the artist

I doubt the artist would ever be "fully" replaced, or even mostly replaced. People very much care about the artist when they buy art in pretty much any form. Mass produced art has always been a thing, but I'm not alone in not wanting some $15 print from IKEA on my wall, even if it were to be unique and beautiful. Etsy successfully sells tons of hand-made goods, even though factories can produce a lot of those things cheaper.
