The lack of empathy is incredibly depressing...
Jobs have been automated since the industrial revolution, but this usually takes the form of someone inventing a widget that makes human labor unnecessary. From a worker's perspective, the automation is coming from "the outside". What's novel with AI models is that the workers' own work is used to create the thing that replaces them. It's one thing to be automated away, it's another to have your own work used against you like this, and I'm sure it feels extra-shitty as a result.
The whole point of art is human expression. The idea that artists can be "automated away" is just sad and disgusting and the amount of people who want art but don't want to pay the artist is astounding.
Why are we so eager to rid ourselves of what makes us human to save a buck? This isn't innovation, its self destruction.
As far as money goes... long run artists will still make money fine as people will value the people generated (artisanal) works. Just as people like hand-made stuff today, even though you can get machine-made stuff way cheaper. You may not have the generic jobs of cranking out stuff for advertisements (and such) but you'll still have artists.
