The term “smart city” fails to fully capture the integrated data system that is the Pudong New Area of Shanghai. Chinese authorities call it the “city brain,” a centrally controlled A.I. center that surveils and manages the city and its inhabitants. It offers a disturbing preview of future urban governance, built on a previously unimaginable level of monitoring and control. Since 2017, this system has linked hundreds of government databases to tens of thousands of sensors, effectively turning an entire urban district into a single, real-time data object.
Officials defend the surveillance for its tangible rewards: cleaner neighborhoods, faster emergency response, smoother traffic, and better protection for isolated seniors. Those benefits help explain why many citizens accept the system. But the costs are equally real. It normalizes penetrating, constant visibility, the steady expansion of behavior-based penalties, and an infrastructure that is also used for political and social control.
