We are constantly exposed in public. Yet most of our actions will fade into obscurity. Do you, for example, remember the faces of strangers who stood in line with you the last time you bought medicine at a pharmacy? Probably not. Thanks to limited memory and norms against staring, they probably don't remember yours either.
This is what it means to be obscure. And our failure to collectively value this idea shows where we've gone wrong in the debates over data and surveillance.
