AI "Artists" are idea guys. They don't care about the process or the knowledge or the experience of creation, only the Content that gets produced that they can consume. They're middle managers claiming the work created by the skills of the workers under them as their own effort. Image generators simply allow them to do a corporation and avoid paying people for those skills or putting in the effort to learn themselves. It's just a new form of coloring books, only created using ethically dubious methods because the companies creating the programs are likely violating fair use laws.

Edit: This isn't to say that people who use coloring books are inherently bad or anything, but when you're trying to pass your page from a coloring book off as a gallery-worthy exhibit and the book was made by a company tracing artwork and using it without permission to make a profit? Yeah, then you're a bad person. Especially if you go on to talk down to artists because you made yours so quickly, etc.
