The second life/metaverse/ virtual reality concept will never be widely accepted by the majority of the populatioj because it just isn’t what the vast majority of people want. They want communication methods that compliment their real world lives.

It's the same reason that urbanization collapses every time it gets out of hand, as it did in Babylon and Rome before us. The majority of the population doesn't even WANT to live in an artificial environment, no matter how hard those who wield power attempt to push it on everyone.
