I think this is only true in a vague and abstract way. In reality, AI devalues labor (in general) and the worth of artists (in specific).

Good art requires good patronage and institutional support in turn. No one will have time to produce the next Mona Lisa if they're barely able to make end's meet working a slavish factory job. That's doubly true when the vocations that supported artists—either antiquated, modern, or contemporary (painter, typesetter, graphic designer, etc.)—vanish because AI can do "just about as well."

Art isn't just a divine presence gracing the souls of those deemed most worthy, it's a collection of skills and knowledge that must be built by community over decades of struggle.

On top of the generation of slop, AI is removing some of the final protections that hold these pillars up. That is what should keep us up at night.
