Jay Graber’s got jokes. As the Bluesky CEO took the stage for her SXSW keynote on Monday, she wore a black T-shirt with black lettering across the chest, which declared, “Mundus sine caesaribus.” Or, “A world without Caesars.”
Her shirt is nearly identical to one that Mark Zuckerberg wore (and designed) at Meta Connect last year. But Zuckerberg’s shirt had a bit more of a dictatorial vibe: “Aut Zuck aut nihil.” It means “Either Zuck or nothing,” playing on the Latin phrase “Aut Caesar aut nihil,” comparing himself to Julius Caesar.
This isn’t just an empty jab; Bluesky’s entire architecture is built around never giving too much power to one person, whereas Zuckerberg owns so much of Meta that he couldn’t be ousted, even if his board wanted him to be.
Et tu, Brute? Then fall, Caesar.
