You can tell Buterin is really smart (and focused) within a few minutes of talking to him about Ethereum. He showed up a few minutes late to an event I helped coordinate. Given his personality, I just assumed he had been off somewhere lost in his thoughts or finishing some critical task; it would never cross my mind that he took the event less seriously or meant to be impolite.

That's how I'd take it, but the author reports that Novogratz saw it differently.

He's probably used to doing what he wants since he works for himself.
