OK, so he said that classical music and the community around it is more rigid than most newer forms of music and their communities, and that it's dying, and the former might cause the latter. What is so unexpected, I wonder
Unexpected not perhaps for a vast audience, but for me. What you didn't mention was perhaps the core of the post: Classical music isn't dead, it's living and breathing and subject to interpretation. Then the points you mentioned carry with them certain implications, namely that classical music could benefit from irreverence and innovation, and that modern music would benefit from classical music's being made more accessible.
