If you care about music: at least 100 years, almost certainly much longer. I don't think any of us in this comment section will live to see an AI that truly understands human music.

If you care about money and don't mind making the world a more terrible place: humiliate a few dozen human classical pianists by making them record hundreds of hours of motion capture, invest in engineering a good robo-arm, and I would guess in 5 years you'd have something passable.

I would think self play and record would be enough to iterate. chess engines don’t really need any human games any more and can learn from self play from scratch. I don’t see why music would be different.

Games are "easy" for reinforcement learning because they have win conditions that can be automatically evaluated. Music isn't really like that.
