Whatever else this emergent "creative AI" phenomenon may or may not do, it's definitely touching nerves in people who still believe there's something ineffable and transcendent about the creative experience.
Stable Diffusion is literally copy-pasting existing artwork. It's not creating anything new.
If anything, this sort of "AI" only makes human ineffable creative experiences even more valuable, because without it there would be no training set and no "AI".
Whether or not its creating something "new" is debatable, but its clearly not copy pasting. It is basing the artwork on a combination of other sources, nothing is created de novo, but that is very different than copy & pasting
