What is strangest in the recent waves of young arrivals in Silicon Valley is that they tend no longer to be downtrodden geniuses rejected in the playing of social status games, but sterling alpha males. Legions of perfect specimens seem to have grown up in manicured childhoods, nothing scrappy about them. When children started to be raised perfectly in the 1990s, chauffeured from one play date to the next, I wondered what world they would want as adults. Socialism? Facebook and similar designs seem to me continuations of the artificial order we gave children during the boom years.
