The big money is where mass audiences are. Music's infrastructure is for a large part dependent on it. It encompasses everything from instrument manufacturers to piano teachers to concert organizers to masterclasses. If --as assumed the post I responded to-- software starts producing better music than people, or does so cheaper, or gets more clicks, etc., the infrastructure will disappear. It'll take a few decades, but that can kill off teaching and affordable instruments, taking everything except amateur music for the wealthy with it.
