Regarding point 2: I think most people cannot destinguish between "genuine" creativity and artificial almalgamation of training data and human provided context. For one, I do not know what already exsists. Some work created by AI may be an obvious rip off of the style of a particular artist, but I wouldnt know. To me it might look awesome and fresh.

Furthermore, I think many of the more human centric thinkers will be disappointed at how many people just wont care.
