I'd say there's a good chance both of those artists are going to grow "beyond" the artist they are emulating (and by "beyond" here I don't mean better than but rather grow into something unique).
Lots of bands (nearly all?) learn their craft by playing covers. At some point the artists in the group start to find their voice.
I suspect AI never will.
Same with copilot; people copy shit from GitHub and SO all the time without mentioning copyrights and a lot of code people cough up is just ‘stolen’ from someone without remembering who/where it was; what’s the difference?
