Overview

• During a cooking segment, the Live AI feature offered out‑of‑context instructions to chef Jack Mancuso, repeating that base ingredients were already combined when they were not.
• Mark Zuckerberg then failed several times to accept a WhatsApp video call onstage, leaving a persistent ringtone and drawing audible laughter from the audience.
• Zuckerberg initially pinned the mishaps on the event Wi‑Fi, a rationale questioned by tech reporters who noted the behavior resembled software errors rather than connectivity loss.
• Meta CTO Andrew Bosworth later said the phrase “Hey Meta, start Live AI” triggered every Ray‑Ban unit in the venue and overloaded dev servers, and he blamed a never‑before‑seen display bug for blocking the call acceptance.
• The failures have gone viral and sparked debate over product readiness for the $799 Ray‑Ban Display glasses, even as some hands‑on testers and analysts argued that doing risky demos live can bolster credibility when other features work.
