From a point of view, I might even agree with Zuck's asinine statement. When I was in my 20's, I had no idea how many things I truly did not know. So, in my limited "fresh out of college" way, I was pushing maximum intelligence. As the years have flown by, I've learned just how vast many fields are. Introspectively, I've learned that I'm not the brightest mind in any given room. As a matter of fact, I've just barely scratched the surface. Many, as they get older, realize this harsh reality. For me, I was probably very smart... and completely ignorant. In tech, this is inflated as we seem to rediscover old paradigms every few years, yet we look at those that may have lived through an earlier "discovery" as "irrelevant geezers". Many of could never dream to achieve the level of things that Alan Kay has forgotten, but we sure will treat his contemporaries as worthless. Zuck will get there some day. And I doubt history will remember his as a great visionary.
