Art is a human expression of an aspect of life, a human reflecting this aspect of life in a manner betraying a comprehension only possible with the emotions and understanding of a human facing our complex society, their limited frame of reference, and describing their situation through the mediums we call "Art".
Art is not pretty pictures. Art is a complex, multi-dimensional communication medium between highly complex, self aware, comprehending entities. AI and AI generated "art" has none of these qualities. These are pretty pictures with an interesting technological backstory. They may be sold as art to unaware consumers, but they are less "art" than a bikini girl poster.
