I think much of the debate is beside the point. For instance, if I heard a piece of music that I found beautiful, and then discovered it wasn't written by a human, I would then find it less meaningful and interesting than if it were written by a human. I don't find that inconsistent, and it's just because I find some of the meaning of music in the fact that it came from a human. There's a difference between music that comes directly from translating one's personal feelings and emotion, and music (even if it's the same sequence of pitches) that comes from a simulation, even if that simulation technology was written by a bunch of humans that have their own artistic impulses. The computer-generated piece may be interesting and worthwhile, but the source of the music is part of the experience for me.
