We make three mistakes: the first is underestimating the quantity of information that we produce every day; the second is depreciating the value of that information; and the third is thinking that our principal problem is a distant and super powerful agency that is called NSA. And it is true that NSA has the major access, better resources, the best tools, but they don’t need any of that to spy on us, because we have everything there; we live in glass houses.

There are thousands of ways to be in the wrong place at the wrong time, and sometimes you don’t even have to move. In Holland they had a census. It was a census that included religions with high devotion rates in the world. They wanted to know how many Protestants, Catholics, Jews they had to know how much money they had to put in each community, in each church or synagogue. What happened? When the Nazis came, they had their homework done. Only 10 percent of the Dutch Jews survived in the Second World War. If that database hadn’t exist, the figures would’ve been very different. What I mean is that our problem isn’t the NSA, neither our corrupt governments, neither ambitious companies that want to sell our data, neither bad people, and it has nothing to do with their intentions, nor with their bad intentions. The problem is that the very existence of that information makes us vulnerable in the ways that we can’t anticipate right now.
