2. miasma is a negative word (means repulsive)
I agree however, it is actually one of the reasons that more well-off people tend to socialize less: other people are not always "wonderful"
Being poorly presented and inarticulate is a form of privilege - it's traditionally associated with academia, but with the rise of the "computer nerd" stereotype, it has increasingly slipped into other venues. What comes to mind is Tfue, the world's top Fortnite player, whose Twitch streams largely consist of him grunting "uuggggghn" and complaining about "stream snipers" with coarse language. He gets millions of viewers.
2 - Apologies, I was misusing the word
A requisite, it isn't. But, for people living in cosmopolitan cities, or people who have an open mind about the world, of course it is.
The screen and the Job have no volition of their own. It's humans themselves that choose to spend more time with them instead of interacting with nearby humans. And this is happening despite the fact that we 're no longer in the industrial age, and people don't need to live near the factory where they work. The Job provides people with enough money to frequently escape from nearby people (travel, or "experiences"), money to move in upscale tiny apartments where they can be alone in a crowd, or to move in comfy suburbs where they can be alone physically. It seems highly-paid people choose those, and it is lower class people that keep socializing with their neighbours.
I presume many of those people do not idolize their relationships with other humans as the most precious thing in the world. They weigh them against the freedoms afforded by money and technology and act accordingly.
