I suspect the mechanism of that will be that Disney lawyers and/or lobbyists will start throwing their weight around once AI trained on Disney media is making money for someone other than Disney.
Sure we do, AI changes nothing. I could have made the same content manually and it still wouldn't be legal because of the IP ownership on the characters.
the point is the opposite, the AI cannot receive royalties because it is not entitled to copyright its work; unless it's changed, there will be no royalties for anybody including SkyNet
Of course future industrial foundational models will be bought and paid for (and royalty free) for the companies that assemble them.
