Even calling it AI 'art' feels wrong to me, I refer to them as AI generated images, and that doesn't sound so invasive anymore.
Besides the fact that the engines steal from their copying sources, the only and single utility I can see for AI images are playing with a machine. Giving it some funny words and seeing what comes out, nothing serious, something in the likes of "make up a flag for unicorns eating carbonara", and having fun with what it makes, but nothing further.
