I have the same issue with AI generated music : it can be quite good to say the least.
But I deeply feel that art only matters if there is an artist. The artist wants to convey something.
What makes you uneasy (if you are like me) is that a machine deliberately created emotions in your brain. And positive emotions, at that. It’s really something I can’t stand.
I different way of reframing this point is looking at some of the modern art that's highly celebrated, without the human component of what it represents, the art itself isn't that good.
So, the guy who suspends buckets of paint with a hole in the bottom to make patterns has an idea of what he's creating. The guy who just put a few strips of electrical tape in different colours had an idea of what he was trying to convey. The guy who flings paint against a wall also has an idea of what he's creating. The guy who made all the white paintings. All that art is trivial to copy in the same style, maybe even an exact copy for the electrical tape, but it's the artist's intention that makes it worth more than a toddler's painting.
Personally, I think most of that abstract art is pointless, because I don't really see how the artist's vision is represented by whatever the mess they've created is, but I definitely understand that at least they had an idea that they wanted to convey. A machine creating the same thing has no meaning behind it, it's just a waste of paint and canvas.
