This tech works, and the only reason we don't have this in the US is because of our cultural and political aversion to mass surveillance. I'm genuinely curious of what this leads to in China, because this tech is easy enough to deploy if you're willing and politically able. What I'm cynical about is that I don't think China is competent enough to safeguard the data it collects, or forever keep it out of the "wrong hands" like the last guy in the video claims. It's hard enough for US government agencies to protect data that should be privileged (police often run illegitimate checks on license plates), I can't imagine China can prevent its various factions from abusing this power. It'd be ironic, but the incompetencies of their bureaucracy could actually lead to their own downfall by way of this technology (their mass surveillance apparatus) somehow getting coopted by dissidents. There's a misconception that China somehow has an iron grip over its people because it's authoritarian, but if that were true they'd have weeded out corruption.
