I feel like this also plays into, and off of, political division. I have had a great number of people who would have been friends, or at least acquaintances, ex me completely for one moment of political disagreement. I also figure the more isolated you become from direct human contact, the more the increasingly-tailored information you see confirms your own dumb ideas. These dumb ideas then become your deepest-held convictions, and you ex the people around you because of just how disturbing the disagreement seems. In addition, finding people to date and have romantic relationships is pretty weird these days. On the one hand, there are dating apps, which seem like they would give you a lot of opportunity to meet new people, but mostly just give you enough information about people to swipe left. If you're a guy, also can no longer court the single women at your employer (even from other departments) without potentially imperiling your entire livelihood. Most of the guys I talk to from a generation or two before me say they met their lifelong friends through a friend or through somebody they were dating, often through people they no longer talk to. It seems like there are a lot of factors, mundane and complex, that could contribute to isolation these days, especially if you're a 7 or below.
