After decades away from music, Jon Jay returned at exactly the moment AI arrived. Everyone was reacting. He didn't. Not because he wasn't paying attention, but because he'd spent 20 years thinking about what music actually is and what it's actually for. The answers made AI considerably less frightening to him than it seemed to be to everyone else. As a result he uses music to explore the world on his own terms, writes about what he finds, and watches what taking sides reveals about the entire human race. And he wrote it all down in his book, "The Last Musicians On Earth?".
