This article and most people I have seen so far, get the concept of metaverse wrong. It's much simpler conceptually (though exceptionally hard technically) than people understand.

The metaverse is the result of instrumenting the real world to capture and interact with the data the real world provides. Think "Digital Twin" of the world that refreshes at 100Hz.

It's not a place you go, it becomes the landscape you live in, because everything becomes a data source.
