CEO Mark Zuckerberg unveiled an ambitious lineup of next-gen tech, including the second-generation Meta Ray-Bans, a new neural wristband, Meta Ray-Ban Display glasses with a built-in heads-up display (HUD), and a pair of sports-focused smart glasses developed in collaboration with Oakley at Meta’s annual Meta Connect event on Wednesday.

However, a technical glitch occurred during a live demo of the Meta Ray-Ban Display and neural wristband. The Display glasses offer a major upgrade beyond voice assist and camera features from the original Ray-Bans. The new glasses feature a heads-up display on the right lens that delivers notifications, directions, and more without needing to check your phone, the Business Insider reported.

In the demo, Zuckerberg used the neural wristband to send messages to Meta CTO Andrew Bosworth, showing off the device’s subtle gesture-based typing capabilities. But when Zuckerberg tried to initiate a video call using hand motions, the system failed to respond. He repeated the gestures several times without success until Bosworth came to the stage in person.

“This WiFi is brutal,” Bosworth said. “Yeah, I don’t know,” Zuckerberg replied. “We’ll debug that later. You practice these things like 100 times, and then you never know what’s going to happen.”

“I promise you, no one is more upset about this than I am,” Bosworth added. “Because this is my team that now has to go debug why this didn’t work on the stage.”

The video quickly went viral, amassing a range of reactions from tech enthusiasts. “Not really believable to be a WiFi issue,” a user wrote. “I wanna see the raw uncut footage of him yelling at the team after,” another user commented.

“This is so scary! And not even slightly interesting. The way tech giants are using these technologies to identify people and get info. Shame,” a third user reacted.

Despite the hiccups, Zuckerberg called the unveiling of the Ray-Ban Display and neural wristband integration “one of those special moments” for Meta.

To highlight Meta’s vision that AI should serve people, not just “sit in a data center,” Zuckerberg brought food content creator Jack Mancuso on screen for a live cooking demonstration using the upgraded Ray-Ban Meta glasses. But the moment quickly turned awkward, the report said.

When Mancuso asked the AI assistant to show him how to make a “Korean-inspired steak sauce”, things didn’t go as planned. Instead of guiding him through the initial steps, the assistant skipped ahead, suggesting he addsm soy sauce and sesame oil without explaining the process. Mancuso repeatedly asked, “What should I do first?”, but the AI failed to respond directly, instead insisting, “You’ve already combined the base ingredients, so now grate the pear and gently combine it with the base sauce.”
