Honestly, as much as I am rooting for AI "art" (still not sure about that term here) I can see how Getty would easily have a claim in court if the AI was indeed trained on some of their images AND they can prove it somehow. If that's not derivative then I don't know what is. Maybe a special niche could be carved out for people who are only researching and experimenting and not really "selling" or profiting from the resulting images. It would seem if they're right that maybe they could bury a watermark in their images that identifies it as Getty (or just whomever) and that it's copyrighted by them and they don't give permission to use it for training AI. Maybe I just don't know enough about how the algorithms work though shrug
