if it [AI] “creates” something pleasing: So what?
One thing I appreciate about music is that it came from another human person. They are communicating something to me.
Consider a world where one does not have actual friends; they have a robot that pleases them. They wind up "pleased" but do they wind up "human"?
I don’t think so. Not where I want to go.
Music is mathematics.
Music is analyzable as mathematics.
It’s also analyzable as physics. As emotion. As gesture. As language.
Reducing it to mathematics is one choice of how to deal with the phenomenon of music. But just one choice of many others.
And even if mathematics -- someone has to do the analyzing, write the algorithms, etc.
