100% on the restrictions.
The thing is, I have zero optimism for an "acceptable" solution, especially given that -- big winners in the space of "using other peoples content" have NEVER followed the law. It just doesn't happen.
Along with all the great freely-sampling records of the past, Google, Youtube, and lately Github Copilot and the DALL-Es all have/had in common that they essentially disregarded copyright law in the beginning and just created. Some might say "flagrantly stole."
It's odd because as a lawyer I should have a solution. But I'm starting to think there is no good, "legally acceptable" one -- if the goal really is innovation and creativity.
