Meta’s AI Glasses Demo Fails Live as Zuckerberg Struggles with Neural Interface

Mark Zuckerberg has experienced a series of embarrassing technical failures whilst demonstrating Meta’s new AI-enabled smart glasses at the company’s Connect 2025 conference in California. The Meta CEO struggled repeatedly to execute basic functions with the Ray-Ban Meta Display glasses and accompanying neural interface wristband, forcing him to abandon multiple live demonstrations.

Context and Background

The technical difficulties occurred during what was intended to be a flagship presentation of Meta’s latest consumer hardware at the developers conference in Menlo Park. Zuckerberg had opened the event with ambitious claims about “superintelligence” being “the most important technology of our lifetimes”, positioning AI as something that should “serve people, not just be something that sits in a data centre automating large parts of society.”

The demonstration began promisingly, with Zuckerberg walking to the stage wearing the glasses and showing the audience his perspective through their integrated camera. However, problems emerged when he attempted to showcase the AI features during a video call with chef Jack Mancuso, where the AI assistant provided incorrect cooking guidance and failed to respond properly to questions.

The situation worsened when Zuckerberg tried to demonstrate the neural interface wristband, designed to allow typing through minimal hand gestures by detecting electrical signals in muscles. Despite multiple attempts, he was unable to successfully answer incoming video calls, with “missed video call” alerts accumulating on the display whilst the audience sat in silence.

Looking Forward

The failures highlight the ongoing challenges facing AI hardware developers as they attempt to integrate sophisticated artificial intelligence capabilities into consumer devices. This incident follows a pattern of high-profile AI demonstration failures, including recent mishaps at Google events where similar smart glasses and translation features have malfunctioned during live presentations.

The technical difficulties raise broader questions about the readiness of AI-powered wearable technology for mass market adoption, particularly given Meta’s significant investment in the sector. Industry observers note that whilst demonstration failures don’t necessarily indicate fundamental product flaws, they underscore the complexity of delivering reliable AI experiences in real-world conditions.
