Daniel Akst:

Americans, plugged in and on the move, are confiding in their pets, their computers, and their spouses. What they need is to rediscover the value of friendship.
Science-fiction writers make the best seers. In the late 1950s far-sighted Isaac Asimov imagined a sunny planet called Solaria, on which a scant 20,000 humans dwelt on far-flung estates and visited one another only virtually, by materializing as “trimensional images”–avatars, in other words. “They live completely apart,” a helpful robot explained to a visiting earthling, “and never see one another except under the most extraordinary circumstances.”
We have not, of course, turned into Solarians here on earth, strictly limiting our numbers and shunning our fellow humans in revulsion. Yet it’s hard not to see some Solarian parallels in modern life. Since Asimov wrote The Naked Sun, Americans have been engaged in wholesale flight from one another, decamping for suburbs and Sunbelt, splintering into ever smaller households, and conducting more and more of their relationships online, where avatars flourish. The churn rate of domestic relations is especially remarkable, and has rendered family life in the United States uniquely unstable. “No other comparable nation,” the sociologist Andrew J. Cherlin observes, “has such a high level of multiple marital and cohabiting unions.”
