Mark Zuckerberg's Meta AI glasses demo went wrong live onstage — twice (www.businessinsider.com)

At Meta Connect 2025, Mark Zuckerberg’s live demos of the second‑generation Meta Ray‑Bans, a new neural wristband and the Meta Ray‑Ban Display with a right‑side heads‑up display (HUD) glitched twice. During a cooking demo, the glasses’ voice assistant skipped ahead—telling creator Jack Mancuso to grate a pear after allegedly “already” combining base ingredients—while ignoring repeated prompts to start at step one. Later, a wristband gesture demo failed to trigger a video call on the Ray‑Ban Display; both incidents were blamed on spotty conference Wi‑Fi and onstage connectivity problems, with CTO Andrew Bosworth promising to debug the wristband. The misfires matter because they expose how fragile real‑world multimodal wearables still are: voice agents, gesture recognition and HUD features often depend on reliable network connectivity, low latency and robust context/state tracking to maintain task flow. The cooking error suggests shortcomings in dialogue state management or step‑tracking; the wristband failure highlights sensor/gesture classification or connectivity/handshake reliability. For builders and researchers, the takeaway is clear—edge/online fallbacks, resilient intent/state handling, and thorough stress testing in noisy network environments are essential for consumer acceptance of always‑on, wearable AI. Despite the hiccups, investor reaction was muted and audience morale remained high.
