It’s not just the telling slip of the tongue, when he very normally remembers once being human, but the way that he then reassures the audience of his humanness by logically explaining why, no, he is still human. It’s a good tipping-off point to remember other wonderful moments of Zuckerbergian “humanity” past.

Howard Dean’s campaign got upended by an awkward yelp; Jeb Bush’s did by a thousand tiny listless moments of glassy-eyed ineptitude. Over the next few years, Zuckerberg will make both of those candidates seem like Bill Clinton by comparison, but the Democrats will probably still run him because they are dogmatically tied to the vanishing myth of the centrist swing voter. Nothing says “middle America” like erstwhile human Mark Zuckerberg, after all.
