I agree. The PBS show Frontline recently did a program on the Uyghurs, called China Undercover:

Often PBS programs are free online for a short period after airing, and then you have to be a member to view. But it appears this one is still free.
The technology is state of the art. Even Uyghurs who are not in a concentration camp are being monitored constantly as if they were. I don’t recall that it is in use yet in other parts of China, though it seems likely that it will be. I believe it is currently more like a model that could be rolled out elsewhere. They also mentioned how they could market it to other countries, such as
allies of theirs around the world.
