But scale and accessibility are absolutely a new class of problem.
In the 1960s you could pay thousands of people to watch hundreds of cameras and listen to hundreds of phone lines to monitor people, but the cost was so enormous that unless you were in East Germany or Moscow it wasn't a realistic threat model.
Now with computers we can cheaply have thousands of cameras with cheap storage that's retained forever and automatic image processing that means everyone is exposed to that kind of surveillance, which is a brand new problem.
