Punk etc which came afterwards was also very silly, and also mostly wasn't very good at all, because it was fashion and performance art and social criticism and musically quite conservative and dull in addition to being amateurish. None of which stopped it from being awesome in its own way, which explains why Robert Fripp played guitar with The Damned while King Crimson was on hiatus, because fun is fun and genre wars are just publicity stunts and you would have to be a rock critic to fall for it. Prog rock is really wonderful and there's more fun stuff than anyone could ever listen to, and that's why 50 years of music critic complaining has failed to kill it.
