The talk he gave on "sousveillance" that was captured in written form in "The Internet of Money":

"“One of my favorite words is a French word: sousveillance. It is the opposite of surveillance. Surveillance means to look from above; sousveillance means to look from below. In their dream of nation-states controlling all of our financial futures, they made one major miscalculation. It’s a hell of a lot harder for a few hundred thousand people to watch 7 1/2 billion. But what do you think happens when 7 1/2 billion of us stare back? When the panopticon turns around? When our financial systems, our communication systems, are private, and secrecy is an illusion that can’t be sustained? When crimes committed in the names of states and powerful corporations are vulnerable to hackers and whistleblowers and leakers? When everything eventually comes out? We have a great advantage because the natural balance of the system is one in which individuals can have privacy but the powerful cannot have secrecy anymore.”
