As a non-famous, non-professional artist this seems like a snobby take. Everyone of these arguments is logically inconsistent with what I know and have experienced using LLM's, stable diffusion, DALL-E, and other generative machine learning algorithms. I wonder what the author would say about plotter artists or CGI artists... would it sound like his take on generative art models?
I guess the only point I would really like to make is this; A closed mind is already defeated.
