Just a realistic thing. Or, a good thing for consumers, a bad thing for producers (and a bad thing for producers who are actually consumers in disguise of a desired lifestyle and/or status).
Good for consumers is highly debatable since we'd lose one more social connection in life. Something we are running a very high debt tab for already.
We would also lose musical knowledge since all the full-time musicians would have to stop playing. Only amateur musicians would remain.
And the "desired lifestyle" / "desired status" would be transferred to the already very, very rich and powerful AI company CEOs. Such an improvement ...
