IMHO what will happen anyway is that at some point the companies will "solve" the licensing by training models purely on older synthetic LLM output that will be "public research" (which of course will have the "human" weights but they will claim it doesnt matter).
It’s important that copyright applies to copying/publishing/distributing - you can do whatever you to copyrighted works by yourself.
Of course, that still won’t make artists happy, because they think things like styles can be copyrighted, which isn’t true.
If we believe that authors should be able decide how their work is used then they can for sure say no machine learning. If we dont believe in intelectual property then anything is for grabs. I am ok with it but the corps are not.
