Who actually wants this? I don't want to stare at digital copies of people I'm trying to communicate with, whilst trapped in a digital maze designed by someone trying to keep me engaged. If the "digital twin" is exactly the same, there's no point, and if it's not exactly the same, it's just weird (i.e. "uncanny").
This "metaverse" is some kind of deranged trap. Social media is a hellscape of misunderstanding and conflict already. A further layer of indirection and reduction in "humanness", in the form of "cartoonifying" everyone, is going to further erode society's foundations.
