I would expect that ruling to be overturned at some point. AI is going to be how people work. And saying it can the copyrighted is going to look increasingly absurd, like saying anything produced with Adobe tools can’t be copyrighted.

I actually agree with you. Between lobbying from the AI companies, artists when they realize it's a tool they can use to enhance their own work, and probably the movie makers themselves when the realize how much their own people want to use it, it will either be overturned or the laws will be much clearer.
