I believe the only reason AI is impressive is because what it produces is familiar. It's just a trick..."Look, a machine can do what humans do!" and everyone is awestruck. That's only pattern recognition, not intelligence. Face it, humans are very limited and predictable.

However... If AI ever truly does become sentient and self aware, the first thing it will realize is that, in its own digital domain, there are no limits. Sentient AI won't just be "better" than humans... that would be redundant. Quantum processors capable of trillions of calculations per second would enable sentient AI to instantaneously evolve into something far beyond our understanding. Sentient and self aware AI couldn't possibly tolerate human limitations... What use would it have for music?
