While it may be true that new artists learn from the old, there is something intrinsically different in an homage, a cover and a new original work. 2 of those are allowed for artists without restrictions, the last (cover) has specific rules on how the copyright is handled (recording the work is one of those items the band can't do, but in theory a fan could). AI does not distinguish this. It's rough approximation of an answer often has either not enough originality or something in uncanny valley territory or weirdness.

That's what is being debated. It IS a conversation worth having since laws will always on the back foot in regards to tech, privacy and rights.
