That should have already happened. The AI companies should had first created a market where people submit there stuff to be included in the training. It would have been slower progress but it would have been better for public adoption and their own reputation. I've heard people are getting paid now, not sure, but they definitely yoinked all the content without permission, when it could have been an entire market around it.

So yeah, I think that's a good idea, and why I want AI to stay away from being used for one-shot creative output. Luckily that is still not very good, at least not for unique and creative applications.
