Elon Musk is missing from the famous photo (http://victorstuff.com/wp-content/uploads/2013/09/paypal.jpg) because he received an innovator of the year award in Chicago at the same time as when the picture was taken.

The YouTube founders, Chad Hurley and Steve Chen, were not allowed to participate in the photo because the corporate handlers at Google didn't want them to be linked to the mafia ;)
