Mark Zuckerberg Humiliated as AI Glasses Debut Fails in Front of Huge Crowd
At Meta Connect 2025, Mark Zuckerberg unveiled Meta’s latest Ray-Ban AI smart glasses and a neural wristband in what was meant to be a groundbreaking showcase. Instead, the live demonstration was marred by technical glitches that left the audience baffled and turned what should have been a triumph into an embarrassing moment for the tech giant.
The Cooking Demo Disaster
One of the most anticipated segments featured chef and content creator Jack Mancuso, who attempted to use the “Live AI” feature of the smart glasses while preparing a Korean-inspired steak sauce. The system immediately stumbled, incorrectly stating that Mancuso had “already combined the base ingredients” when he had not. When he asked the AI what to do first, it failed to give a coherent response, derailing the demo in front of the audience.
Video Call That Wouldn’t Connect
In another showcase, Zuckerberg himself tried to answer a video call using the new glasses paired with the neural wristband. The ringtone played loudly, but when he attempted to accept the call, nothing happened. Meta’s CTO Andrew Bosworth later explained that the display had gone to sleep at the wrong moment, preventing the answer prompt from appearing even after the device was re-activated.
Overload and a “Self-DDoS”
The company later revealed that part of the failure stemmed from an unexpected overload. When the “Live AI” cooking demo was triggered, every Ray-Ban Meta glasses unit in the building attempted to respond simultaneously. This caused a flood of requests that overwhelmed a development server, essentially creating a “self-DDoS” attack that crippled the system.
Embarrassment or Growing Pains?
While the mishaps left Zuckerberg visibly frustrated on stage, Meta insisted the problems were tied to the unique circumstances of a live event rather than fundamental flaws in the product. Under normal conditions, the company claims the glasses work as intended.
Still, the episode highlighted the risks of showcasing unfinished or experimental technology in front of a global audience. What was meant to be a bold display of innovation became instead a viral reminder that even the world’s biggest tech companies are not immune to live demo disasters.

What Went Wrong
-
Cooking Demo Failure
In one segment, chef and content creator Jack Mancuso attempted to use the “Live AI” feature of the new smart glasses to guide him through making a Korean-inspired steak sauce. The AI misinterpreted the stage of the cooking process, telling Mancuso he had “already combined the base ingredients” even though he had not. When asked what to do first, the AI failed to respond correctly. Business Insider+3The Daily Beast+3Tom’s Guide+3 -
Video Call Glitch
In a separate segment, Zuckerberg tried to take a video call via the glasses and wristband setup. Though the ringtone was audible, he was unable to answer the call. Meta CTO Andrew Bosworth later explained that the display had gone to sleep at exactly the moment the notification arrived, and even after waking it, the answer prompt did not appear.

Overload and “Self-DDoS”
The company revealed that during the cooking demo, when “Live AI” was activated, all of the Ray-Ban Meta glasses present in the building responded, leading to a traffic overload. The system was routed to a development server meant to be isolated, but because many devices accessed it simultaneously over the Wi-Fi, it overwhelmed the infrastructure. Bosworth described this as a kind of “self-DDoS.” Business Insider+1
What Was Accurate, What Was Overblown

Accurate: There were multiple failures during the demo (both in the cooking demo and in taking a video call). The Daily Beast+2Tom’s Guide+2

Accurate: Meta officials later acknowledged the glitches and provided technical explanations. Business Insider+2Tom’s Guide+2

Overblown/Sensational Elements: Words like “humiliated” are opinion-laden. While many in the audience found the glitches embarrassing, Meta’s leadership framed the issues as serious but technical failures rather than signs of fundamental product flop. Also, implying that every feature failed would be misleading—some functions still generated positive feedback. Tom’s Guide+2The Week+2
Takeaways
-
Live tech demos are risky; even small oversights in infrastructure (e.g. too many devices, overloaded dev server, Wi-Fi issues) can cause major breakdowns publically.
