no control leads to corruption

"Any government that can automatically generate an intimate profile of every one of ts citizens is a government endowed with a potential for absolute power that will eventually, to use Lord Action's phrase, corrupt absolutely. Few civil liberties are likely to survive such capacities in the hands of increasingly panicky authoritarians who run the embattled old beaucracies of the Meat World.
..
any govermnent which can see everything we do all the time will sooner or later feel compelled to add omnipotence to omniscience, which are, in the Virtual Age, much the same thing anyway."
