Countering recent hype around technology, a leading expert argues that the endurance of dictatorship in China owes less to facial recognition AI and GPS tracking than to the human resources of the Leninist surveillance state. For decades China watchers argued that economic liberalization and increasing prosperity would bring democracy to the world’s most populous country. Instead, the Communist Party’s grip on power has only strengthened. Why? The answer, Minxin Pei argues, lies in the effectiveness of the Chinese surveillance state. And the source of that effectiveness is not just advanced technology like facial recognition AI and mobile phone tracking. These are important, but what matters more is China’s vast, labor-intensive infrastructure of domestic spying.
