There's nothing Disney or anyone can do because the tools are all out there, it just makes it harder for average people to produce said images because of how easily accessible dalle is, they can control that for now. However, after seeing SVD in action I know where this is going, and you can pretty much guess as the writings on the wall, full blast for everyone to see.
In 10 to 15 years, maybe sooner, people will be able to make their own movies with their own characters and stories that will compete with the likes of Disney and other studios, and they can't stop it. SVD is cheesy at the moment, sometimes it produces videos that are just panning or zooming out, but some of the animations it generates are pretty impressive and all it took was 1 picture... I saw like 4 good examples so far of it and its obvious where we are headed. This probably frightens Disney very much, they have the most to lose from this, but its not only Disney.
