What I was trying to say in my reply was that "he is ignoring the fact that people still write classical music" is not a valid point. There are 6.7 billion people on this planet; if there are a couple of people with a hobby, that does not prove anything.
Gotcha. But what if those "people with a hobby" are capable of doing incredible things with music? They'd benefit from being in a field of music that's not neglected for being thought of as centuries-old.
