Somebody said the cooking guy was some influencer person? I noticed that many non-tech people often resort to this excuse, even in situations where it makes absolutely no sense (e.g., on a desktop with only ethernet, or with mic/speakers connected via cable). It's almost like they just substitute "bad wifi" for "glitch".

It's almost certainly a joke. Everyone knows that the demo failed.

Pretty sure it's a meme, like blaming the WLAN cable.

Bad idea to rely on WiFi for an important demo in a crowded environment. It would have worked fine in testing but when the crowd arrives and they all start streaming etc, they bring hundreds more devices all competing for bandwidth.

Zuck should have known better and used Ethernet for this one!
