Meta CTO Reveals Smart Glasses Demo Failures at Connect 2025: ‘We DDoS’d Ourselves’

Meta’s chief technology officer, Andrew Bosworth, has offered a detailed explanation for the highly visible live demo failures of the company’s new smart glasses technology at this week’s Meta Connect developer conference. Dispelling initial assumptions, including those from CEO Mark Zuckerberg, Bosworth clarified via Instagram that the issues were not primarily due to faulty Wi-Fi.

During the event, Meta unveiled three new smart glasses: an enhanced Ray-Ban Meta, the Meta Ray-Ban Display with a wristband controller, and the sports-focused Oakley Meta Vanguard. One notable incident involved a cooking content creator whose Ray-Ban Meta glasses failed to respond correctly to a recipe query, forcing the demo to halt. Bosworth attributed this to a critical resource management flaw: initiating ‘Live AI’ on the demo unit inadvertently activated the Live AI feature on every Ray-Ban Meta device present in the building. This unexpected surge, coupled with isolating traffic to a development server, resulted in Meta’s systems being overwhelmed—a situation Bosworth humorously described as “DDoS’ing ourselves.”

Another demo, a live WhatsApp video call between Bosworth and Zuckerberg, also failed to connect. This, according to the CTO, was caused by a newly identified “race condition” bug where the smart glasses’ display went to sleep precisely as the incoming call arrived, preventing the answer notification from appearing. Bosworth confirmed the bug has since been resolved. Despite these public glitches, Bosworth expressed unwavering confidence in the product’s core functionality, emphasizing that the incidents were “just a demo fail and not, like, a product failure.”
