The big question is whether we enjoy art for the response that it evokes in us, or is it about the process and the individual artist’s message that they want the viewer to see and think about.
The first response would mean that we could legitimately enjoy A.I. art as a new type of art, the human artist being demoted to the position of assistant, or machine operator.
The second, the artist’s “message” would mean that A.I. art would always be viewed as a fake way of producing something that humans have battled with for centuries, and haven’t finished with yet, to investigate nature and reality with our very own depiction of what we see.
A machine on the team doesn’t enhance the ability of the artist’s view of the world, it would take over the process and give us ideas that are always an interpretation of a machine.
