"For decades, in every field, especially work and technology, there has been the implicit assumption that new=improved."

This is not "work" or "technology" - this is art and heritage. Change does not necessarily mean "replacement" in this area, but rather "addition".

With all due respect to Bob Copper, the idea of change in music is not meant to replace what already exists. The works of Michaelangelo are on view for all to enjoy and learn from, but we do not want to discourage artists from creating their own. It is the same thing with music.
