It was never alive to begin with. The Metaverse exists as nothing more than a buzzword made popular by Zuckerberg/Meta. There are no technologies, standards, devices or software driving it. Nobody even agrees on what features it should have.

And on top of that, old pre-buzzword stuff like SecondLife or PlaystationHome are still closer to a “Metaverse” than any of the more recent buzzword filled attempts.
