Google can’t read your mind, of course. But it can read your search history. It tracks a lot of your web browsing, too. Google has an enormous amount of data about its users, and it uses that data to make an unimaginable amount of money from advertising: over $120 billion a year. The company runs a vast profiling machine, fitting people into categories that say who they are, what they’re worth, and how they’re expected to act. Google isn’t just organizing the world’s information; it’s sorting the world’s populations.
