What's coming is post-scarcity for all kinds of intellectual work. There will be nothing to economize: supply of both labor and product will be infinite. I don't want corporations engineering a made up economy where there is none.
Unfortunately, all intellectuals also need to eat, bathe and clothe - areas where no "post-scarcity" is on the horizon (with climate change, both food and water may become less abundant). So an economic system will need to be invented.
Human-sourced styles will become trend, as people seek originality to establish identity in an otherwise indistinguishable world of machine-driven experiences.
There is no definition of "style" here you can rely on without causing just as much harm to human artists as you would be restricting AI art. Everything is derivative of something/someone else after all.
Just like copyright today, even though the individual supposedly benefits from this scheme, it's companies who have greater stake in the outcome.
Suddenly, copping someone's steez becomes a matter of revolution.
