Ironically, the digital revolution was supposed to be an equalizer. The early boosters of the Internet sprang from the counterculture of the 1960s and the New Communalist movement. Some of them, like Stewart Brand, hoped to spread the sensibilities of hippie communes throughout the wilderness of the web. Others saw the internet more broadly as an opportunity to build a society that amended the failures of the physical world. But in the last few years, the most successful tech companies have built a new economy that often accentuates the worst parts of the old world they were bent on replacing.
