Shortly after hopping onstage, Zuckerberg joked that he might need to schedule his next appearance in order to apologize for whatever he was about to say. After a beat, he added that he was just kidding and that, in fact, his days of apologizing are over.

Zuckerberg has had something of a rebrand recently. He raises cattle in Hawaii now, has long bouncy curls and a gold chain, and commissions Roman-style statues of his wife. Onstage, the Facebook founder wore a boxy T-shirt he designed himself alongside fashion designer Mike Amiri that read “learning through suffering” in Greek letters.
