Qualifying art as egoistic is misunderstanding. We do "art" (or any expression, really) to share it. Because we love the effect it has on people. Making them smile, think, wonder, dream... Art in a vacuum is nothing but a senseless waste of time. Fundamentally, art is about relationships.
I agree that AI art is also art. I've seen some stunning generated landscapes that made me want to be there, want to explore and go out.
However it is still an expression of one's feelings, and the way you experience it is an expression of your own feelings. It will always be personal. Sure, event photographers might be replaced by automated cameras (hell, I have plans on doing that myself to some extent), but then the "art" is simply displaced to whoever uses that tool. Maybe an influencer or something.
But ask yourself this: what motivates people to use these tools?
Surely it's for expressing themselves or earning money (or both). That, in itself, will make any form of art personal, individual authorship still applies.
