@dlevenstein I honestly think the only real uses for creative work LLMs will essentially be "inspiration generators," e.g. providing a place to get started, similar to doing a mood board or using an old text prompt list or looking through stock photos etc.
And IMO that would be defensible, because (as an example) you don't have to credit a photo of say New York or Tokyo for inspiring a sci-fi story set in a large metropolis on a distant star many millennia from now
