"For a long time I felt somewhat unique in this regard, but COVID has made my longstanding reality the norm for many more people. Their physical world is defined by their family and hometown, which no longer needs to be near their work, which is entirely online; everything from friends to entertainment has followed the same path."
The unbundling of physical and digital reality is certainly happening, but I also think new forms of rebundling are also happening. Before COVID, I would never dream of calling my daughter in the next room, but now I do it all the time - not (only) because I am lazy, but because the call or text is less intrusive than knocking on the door and therefore has better UX.
To see what's happening as only:
1) "the real world is the combination of the digital world and the physical world and that the real world is not just the physical world."
or
2) "the Metaverse is the set of experiences that are completely online, and thus defined by their malleability and scalability"
is to downplay the combinatorial possibilities of dis-aggregating and recombining the digital and the physical. It feels to me that a certain 'computational style' is becoming widespread tacit knowledge and shouldn't be identified only with the digital/online/virtual.
