Why Meta’s Smart‑Glasses Demo Crashed: Inside the DDoS and Race‑Condition Nightmares

At Meta Connect 2025, Meta's ambitious showcase of three new smart glasses and a neural wristband backfired with two high‑profile demo failures—one caused by a self‑inflicted DDoS from simultaneous device requests and the other by a race‑condition bug that put the HUD to sleep—turning a potential breakthrough into a public embarrassment.
