I agree, there's some sort of federation issue or delay.
I noticed earlier that content from [email protected] is delayed, there are several new threads from the last few hours there that haven't appeared here yet.

Natural immunity to covid has never been accepted as better. You're still a conspiracy theorist with very dangerous things to say

Like other headsets its too bulky. Sunglasses are easy on/off but this and other AR headsets (hololens) are completely incompatible with most people's life. At work its going to mess up hair and makeup, and no one wants tight fitting goggle marks on their face. The Google Glass form factor was ideal but obviously the tech isn't there and the tradeoffs were too high. Maybe AR will be socially acceptable some day but vision pro is too early imo.
