Meta’s Ray-Ban Smart Glasses Stumble Through Embarrassing Live Demos at Connect 2025

At Digital Tech Explorer, we often dissect the future of technology, and few events promise as much spectacle as Meta Connect. However, the recent 2025 livestream delivered an unexpected kind of spectacle: a series of awkward mishaps that suggest the old showbiz adage, “Never work with children or animals,” might need an update to include smart glasses. Intended as a triumphant showcase for the new next-generation Ray-Ban Meta glasses, the event instead laid bare some glaring issues as the cutting-edge technology faltered at nearly every turn.

Meta CEO Mark Zuckerberg introduced these second-generation AI-powered glasses, touting them as a revolutionary device set to “empower people with new abilities” through advanced AI functionality. Yet, as TechTalesLeo observed, the live demonstrations that followed quickly spiraled into farce. The inaugural demo saw chef Jack Mancuso trying to use the device’s Live AI to assist with a Korean-inspired steak sauce. While the AI initially seemed to recognize the ingredients, it conspicuously bypassed the prompt to begin the recipe, instead merely enumerating potential components.

When Mancuso asked, “What do I do first?” he was met with a long silence. After a second attempt, the AI confidently informed the visibly nervous chef that the base of the sauce was already made. Another long pause ensued. Mancuso asked again, “What do I do first?” only to be told, “You’ve already combined the base ingredients,” and instructed to grate a pear into the non-existent sauce. “Alright, I think the Wi-Fi might be messed up,” Mancuso said, sheepishly handing the presentation back to Zuckerberg, who blamed the glitch on the venue’s Wi-Fi connection.

Mark Zuckerberg’s Attempted Live Call Demonstration

Later in the presentation, it was Mark Zuckerberg’s turn. Donning a pair of the Ray-Ban Meta glasses, he aimed to demonstrate a wristband interface controlling the device through muscle movements. After the audience, keen for a live demo, chose it over slides, Zuckerberg tried to answer an incoming video call. Though he successfully responded with a text message via hand gestures, picking up the call itself proved impossible.

“Uh-oh,” the Meta CEO said, frantically rubbing his fingers together to pick up the line. “Well, I… let’s see what happened there. That’s too bad. I don’t know what happened.” Despite multiple attempts and another incoming call from “Boz,” Zuckerberg was left on stage twiddling his fingers as the ringtone echoed through a silent hall. He eventually gave up, stating, “I don’t know what to tell you guys,” before bringing Boz onto the stage to move on from the failed demonstration.

This entire sequence, chronicled here by TechTalesLeo, was undeniably a painful watch. While any presenter can sympathize with a live demo gone awry, these multiple, public failures did little to inspire confidence in Meta’s ambitious new product. From Digital Tech Explorer’s perspective, the presentation seemed to lay bare serious flaws in the current implementation of the technology driving the Ray-Ban Meta smart glasses. It’s challenging to envision many tech enthusiasts or professionals rushing to place an order after such a glaring public display of malfunction. Yet, in the ever-evolving landscape of digital innovation, perhaps there’s truth to another old cliché: there’s no such thing as bad PR. At least the conversation, and the critical analysis of emerging AI hardware, continues.
