Like the 9/11 terrorist attacks in the U.S., the coronavirus pandemic is a crisis of such magnitude that it threatens to change the world in which we live, with ramifications for how leaders govern. Governments are locking down cities with the help of the army, mapping population flows via smartphones and jailing or sequestering quarantine breakers using banks of CCTV and facial recognition cameras backed by artificial intelligence. The restrictions are unprecedented in peacetime and made possible only by rapid advances in technology. And while citizens across the globe may be willing to sacrifice civil liberties temporarily, history shows that emergency powers can be hard to relinquish. A primary concern is that if the public gives governments new surveillance powers to contain Covid-19, then governments will keep these powers after the public health crisis ends," said Adam Schwartz ... at the non-profit Electronic Frontier Foundation. "Nearly two decades after the 9/11 attacks, the U.S. government still uses many of the surveillance technologies it developed in the immediate wake." In part, the Chinese Communist Party's containment measures at the virus epicenter in Wuhan set the tone, with what initially seemed shocking steps to isolate the infected being subsequently adopted in countries with no comparable history of China's state controls. For Gu Su ... at Nanjing University, China's political culture "made its people more amenable to the draconian measures."
