Yes. I barely recall the Black Mirror episodes, but the Chinese "Social Credit" system currently being rolled out should be enough to give anyone pause about just how far their own government may try to go at some point. Also, have you ever watched the Snowden movie? I watched it not long ago and I recall one of his statements at the end very clearly. It said that part of why it was important to do what he did was not that he was against the current American administration (at that time Obama), but rather because if he left the system in place, when a less benevolent leader came to power they would effectively have "turnkey tyranny" at their fingertips. How prescient that wound up being! Can you imagine such systems in the hands of the current American president!
