may be possible one day to ask AI to create songs
Why?
There are no shortage of humans doing it well, though record labels seem determined to promote the poorer ones, we'd be worse off with AI songs.
Humans are self replicating and to an extent self repairing.
There are probably useful things real AI might do, just as there are useful things that can be done with other tools. Probably boring and tedious things that humans don't want to do, like sorting rubbish, being a prison officer or changing nappies.
