Meta、新型AIグラス発表もデモ失敗 原因はWi-Fiでなく自社サーバー

Meta unveiled its next generation of AI-powered smart glasses at the annual Connect 2025 conference, marking a significant push into wearable technology aimed at moving beyond the smartphone. CEO Mark Zuckerberg introduced three new models, including the flagship Meta Ray-Ban Display. However, the keynote was overshadowed by a live demonstration failure of the glasses' AI assistant. While Zuckerberg cited Wi-Fi issues on stage, the company later provided a more detailed technical explanation for the public glitch, highlighting the challenges of deploying cutting-edge AI.

The most notable moment of the keynote was the failure of a live AI demo during a cooking segment. The AI assistant provided incorrect instructions before becoming unresponsive. Meta’s CTO, Andrew Bosworth, later explained that the voice command on stage accidentally activated the “Live AI” feature on every device in the building, causing a self-inflicted Distributed Denial-of-Service (DDoS) attack on their internal development server. This, not poor Wi-Fi, was the root cause of the AI's failure to respond correctly.

A second demo featuring Zuckerberg attempting to answer a WhatsApp call on the glasses also failed. Bosworth explained this was due to a “never-before-seen bug” that occurred when the device entered sleep mode precisely as the call notification arrived. He stated the bug has since been fixed. Despite the on-stage issues, Meta’s decision to attempt a live demonstration was noted as a transparent approach compared to the pre-recorded presentations often used by competitors.

The centerpiece of the new lineup is the Meta Ray-Ban Display, priced at $799. This model features a built-in display for apps and notifications on the right lens. It is controlled by the Meta Neural Band, a wrist-worn device that uses surface electromyography (sEMG) to detect minute hand gestures. This allows users to perform actions like writing text messages by mimicking the motion with their fingers, showcasing Meta's long-term vision for a new computing interface.

Meta also introduced two other models to target different market segments. The second-generation Ray-Ban Meta glasses ($379) offer upgraded battery life and 3K video recording. For athletes, the new Oakley Meta Vanguard ($499) provides a rugged design, integration with fitness apps like Strava, and an IP67 dust and water resistance rating. These products demonstrate Meta's strategy of creating specialized hardware for distinct use cases.

The announcements from Connect 2025 underscore Meta's ambition to establish a leading position in the AI wearables space. The company is competing directly with Apple and Google to define the next major personal computing platform. The demo failures, while a setback, offer a candid look at the immense technical hurdles that must be overcome to deliver a reliable, always-available AI assistant, which remains a critical factor for the mass adoption of such devices.
