The point isn't the achievement, the output. The point is the actual connection. You have to remember that even great music like Bach's is only barely adequate to bridge the terrible interpersonal gap that separates people. The last thing you want to do is create an emphasis on the artifact rather than the authentic human connection. A new way to be inauthentic, by having computer-simulated Bach, why that's as easy as lying.
Truth is what's hard.
The general picture is going to emerge sometime soon of what we can and can't do to a person. I think it's going to be the greatest challenge our species has ever faced. More challenging than nuclear weapons. With nuclear weapons, the only question is, can we survive them or not. Who do we want to be as a species.
