I respectfully disagree with you saying ai generated images are not art, it is "a form" of art, and saying so doesn't equate to saying art is unimportant or that the human aspect doesn't matter. Art is important, the human aspect does matter a great deal. Art is about ideas and means to express them, AI-gen does allow it in different ways than previously but right now you still have a sentient being with an idea to prompt the AI.

What you are saying looks a lot like what people used to say about photography not being art, and fear mongering about photography replacing other forms of art like painting. The opposite happened, photography shaped into its own form of art, and painting evolved to new era of amazing ideas.
