I disagree, at least as far as rhythm and pitch are concerned. For classical music, staff notation is great — but once you get into syncopation, soloing, and the general fluidity that comes with practically all popular music from the past century, it becomes untenable. Seriously, writing down guitar solos in staff notation is just gross. (I've previously written a little about it here: http://beta-blog.archagon.net/2016/02/05/composers-sketchpad...)
