There's an amazing movie created by 101 East on the topic of China's surveillance, called "China's spying Eyes", you can find it on youtube or AlJazeera homepage. For the sake of security, like in Hobbessian Leviathan, the citizens have sacrificed all of their freedoms to a monster, a state and this sacrifice is not proportional. The topic was once proposed by https://www.effectivepapers.com/ and now, investigating even further, it becomes apparent that not only Chinese govt heads to that direction. EU anti immigration programs, implementation of AI at the customs, etc. Those commiting crimes will find the way to do that, while the ordinary people will pay the price. Finally, for the states this a zero-sum game and always win.
