Nah, he's really smart, but implying 1T is a measure of his genius is ridiculous. Not only does it downplay the massive contributions of hundreds of people including Peter Thiel and Cheryl Sandberg, but it ignores the market conditions that led to thefacebook.com going viral, not to mention the Winklevosses, who got paid billions in today's valuation. Do you believe that if Zuck never met the Winklevosses, he would have necessarily built a 1T company anyway, because quantity X of genius must necessarily manifest to F(X) valuation? I think the market violently disagrees with you.
I'm disagreeing with the "just a college kid" portrayal. There are of course a few circumstances greatly helped the trajectory, as did many other smart people help it along. What I'm trying to imprint is that without Zuck being very intelligent, the level of success Facebook would've had would be far far smaller.
