Like everything in nature, socializing has a function, and it has been increasingly eroded by technology. Even a few thousand years ago it was the deciding survival factor. As we move deeper into the information age, it seems more and more inconsequential. In my own life, a broader social circle has mostly proven to be at best good entertainment, at worse it can hurt you, but usually is just wasted time. You meet people, learn their incredibly mundane and predictable lives (not excluding myself here), and then life happens and you don't see them ever again, or at least not enough to make a difference.

Having a social network of people to constantly talk to is not needed unless we go back a few thousand years in time... which, to be fair, could happen with some global catastrophe, however if civilization keeps going, I think socializing will be about sharing thoughts, and not so much about physical proximity.
