It is a tough issue, but legalese will probably start from where and on what and how did this thing train on in order to be able to produce such results. It's similar to (guitar) amp modeling. Eventually they will either have to remove it or license it. I don't see other way. What makes it challenging is that vast majority of things that it was trained on can make a similar claim and it opens the floodgate. Outcome is either youtube-like thing where things exist in certain capacity, but not full or alternative is Napster like destiny where it gets banned altogether. Stakes are now a bit too high for Napster scenario. OpenAI might have a youtube-like angle for licensing with its Sora thing which seems to be turning into its own social network of sorts.
