The thing is, few people actually like art. They like Thomas Kinkade.
Truer words were never said! When we had the galleries, we'd often have people stop in with fabric swatches from their couch or curtains, because they were looking for art to "match." In fact, they were never looking for art, they were looking for decoration. And I guess many will think that AI creates precisely that "adequate" kind of decoration.
I'm certainly not a total naysayer when it comes to AI... it will definitely have its useful applications.
Personally, I will continue to create, because I feel compelled to express what I am seeing in my mind's eye. Sadly, I expect those creations may end up having less and less value in the commercial sense, ultimately pushing art in the direction of being more like a personal journal than something to be shared with a potential audience and/or a commercial motive.
