China has proven that no one needs to "watch" CCTV, because the system will automatically identify everyone in the camera frame. That still requires more resources than mobile app tracking, and it's easier for people to disguise themselves against a camera rather than mobile app tracking, so mobile app tracking is the greater current threat. But CCTV identification will improve and it will be harder to fool, so I don't want that either.
