If a human author is allowed to read and cite other works in their new composition. For example a Stephen King book referencing another author or famous book like Lord of the rings, then ai should be allowed to do the same as provide similar outputs that Stephen King would come to organically. if it's just using themes, show me any book that's not got derivative parts in it at all.
