"As Aaron Bady has argued in MIT’s Technology Review, the language and concepts for privacy evolved in a world where “walls” were still the dominant metaphor. Peeking through a wall was sufficient to prove you violated someone’s privacy. But technology has opened up a brand new world where walls no longer exist, or things exist in so many places that the idea of walls makes no sense. Without them we need new concepts.

As is often the case, the battle between authoritarianism and democracy can do a lot of the mental work. One of the great things about democracy is its ability to check private and government power, as well as creating institutional structure promoting accountability and transparency. And I fear it is the only way out of the situation our country faces."

The point is that the definition of surveillance itself is changing along with the concept of privacy, leading to shifts in previously-stable balances of power. To a very large extent, these changes - which have both positive and negative aspects - are byproducts of a larger technological shift which has already brought far to many advantages to reverse.

In other words, we need to develop new social norms and structures to ensure the safety of what could otherwise be very dangerous system. We don't have to do this from scratch, but the familiar frames of reference do need updating. And that starts with recognizing that "surveillance" by itself, is neither good nor bad (depending on who is watching who, under what circumstances, and why), but that it can easily be either depending on the context.
