The kind of art you're talking about is "high art" and it's a luxury item. The majority of artists don't produce that type of art, and will instead lose out in this scenario.
Ultimately you are talking about art as a product and that means you think all art is captured by Warhol's system of art. Which is what all digital artists overreacting to this also think. It's not the totality of what art is. I like DALL-E. Good work, but now what else is there beyond digital art? Or by pushing digital art to some more extreme outcome?
Yeah, art is vast. It includes me saying "Kerflaffle!!" while I ride a unicycle and fart out a candle in a dimly lit room. But that doesn't usually pay bills and most artists don't do this type of art. It serves a different audience/consumer. It has a different market cap. Let's not confuse oranges and grapefruit.
