Social connections require work, they also are slow and unreliable.
Before the information age, to get to know something, talking was the main way.
But now with books, panels, displays, packaging, signs, internet, GPS, etc., we have access to a huge quantity of information without having to talk to each others.
And we choose to do so because on average it's faster, more accurate, and avoid to deal with annoying people. After all, human relations also include a part of risk.
I lived 2 years in Africa, and there, you don't have that much information immediately available. You are back to talking, creating a social network and playing the game. People are way more friendly there, there is greater solidarity. But things are also way slower, unreliable, and you are a lot more at the mercy of popularity games even in the most simple activities.
This century we have been mutating our lives in deep ways, very fast. And it's not all bad. But we will need some time to reconcile the efficiency of our new life styles with the social needs we have at the primitive level. A few decades is way too short for that to have happened already, especially since we are not done with technical progress.
