I don't think that's really fair... I can see the argument for removing AI generated stuff in part because it doesn't require technical artistic skill (whereas digital art still does, in your ability to observe, draw with perspective, etc.)
But that can easily lead to a slippery slope since it requires more technical skill to make physical art than digital (for one, you can't "undo" anything in physical world.) Where do we draw the line?
Secondly, it will just become more and more subtle as art softwares will subtly repackage such AI tools into their art software packaging. I am willing to bet anything Adobe is already employed an army already to figure out how to do so. How would you tackle that?
So if I skillfully combine multiple AI generated images it's stops being art? What's the difference between someone only using that vs. someone taking parts form random images found in Google image search? The latter very common among digital artists.
