What would the world look like if Facebook succeeded in becoming the Operating System of Our Lives? That status has arguably been achieved only by Tencent in China. Tencent runs WeChat, which combines aspects of Facebook, Messenger, Google, Twitter, and Instagram. People use its payment system to make purchases from vending machines, shop online, bank, and schedule appointments. Tencent also connects to the Chinese government’s Social Credit System, which gives users a score, based on data mining and surveillance of their online and offline activity. You gain points for obeying the law and lose them for such behavior as traffic violations or “spreading rumors online.”
