Some of them can get close to the real thing and maybe just the first step to being almost identical to the real voices.

How long will this last?

I assume eventually artists would be pissed if they covered a song without theiir permission with A.I.

I want to hear Taylor Swift sing "My Neck, My Back."

There are impersonators who could probably sound better. The Hetfield one doesn't even sound close to me. It's an interesting idea but who the hell would want to listen to this stuff? They're soulless versions of the original songs.

I think it's done either for chuckles or as an example of what AI is capable of (or both). I don't think anyone's listening to these for real music entertainment.

Phil Collins singing Michael Jackson. Just when you think it couldn't get worse, it does.

Who knows the technology might get better and they will sound exactly like the real artists

This one sounds close to real
