But no one is complaining about publishing derived work. The issue is that "the robot brain has full copies of my text and anything it creates 'cannot be transformative'". This doesn't make sense to me because my brain made a copy of your book too, its just really lossy.

I think right now we have definitions for the types of works that only loosely fit human actions mostly because we make poor assumptions of how the human brain works. We often look at intent as a guide which doesn't always work in an AI scenario.
