I've been thinking about this concept ever since microsoft debuted a pendant 'life recorder' a few years ago.

I don't know if you've ever read 'The Stars, My Destination", but it's an old science fiction book based on the idea of a change in our abilities that completely destabilizes the current manner of human life.

I believe ubiquitous recording would be an equivalent change. It may be my warped perspective, but I believe an incredible amount of our society is build upon lies and untruths. This sort of technology will create an enormous, disruptive amount of accountability to every single person affected by it.
