The answer nobody's facing is that the system of working for a living is going to have to stop. We all retire, or we're all sacked, pick one. Because eventually ALL jobs, without exception, will be automated. Even in the near term, a lot of jobs you wouldn't expect, ones that look "creative" or "decision making", will be automated.
Playing in a band isn't exactly a job today, but I can't see how it can be automated. It can become less popular or forgotten altogether, but not automated.
Yeah, there's stuff that nowadays is phrased as "a job" because it has to be, that would become "a vocation" when jobs went away. Programming is another obvious example.
Yeah, but it's turtles all the way down, isn't it? She's just software, so in theory someone can metaprogram that as well. If you're writing a generator of virtual performers, are you really "playing in a band"?
You're no longer in the music business but you don't replace musical bands. You can't. You just created a new genre of music while bands happliy bang away.
