Really great read on the history of that picture and those in it.
Otherwise, I will keep my opinions to myself.
I think this (along with many other points in the issue) just help to stress the point that times have changed. I'd be amazed if I met anyone in corps who couldn't read sheet music and learned everything by the rote system.
