Guitar Hero for Conductors?

I just got back from the Dance Repository Theatre’s preview of CanciĆ³n del Cuerpo, which was intriguing enough that I’ll want to see it when it’s finished.

One interesting gimmick William Meadow’s use of Wiimotes to control the score. I can imagine a fun version of Guitar Hero or Rock Band where you conduct with Wiimotes, but I’m not sure I see the value in a real performance (other than the novelty). If you’re going to rely on digital recordings, having a human at the helm is like having a human umpire call balls and strikes: the human element can only add mistakes.

I can understand the appeal of a live orchestra: even my uncultured non-audiophile ears appreciate the difference between a real orchestra and a pair of speakers. But once you have the speakers, what’s the point of having a live conductor? Why wouldn’t you just use the best recording?
