Artstation should separate out ai made art. Ai art is not a tool, it is a service. much like ordering a pizza, it gives you what you ask for but you didn't make the pizza.
It is also my belief that all Ai should be trained on materials which have been obtained through a purely ethical "opt in" process only. And when an artist opts in to train an ai that artist should then receive a cut of any profits gained every time the ai samples thier artworks.
