In 2010, you have roughly 38 billion dollars spent by government on cyber and telecoms security and another 60 billion or so by private corporations. So approximately 100 billion dollars spent on security, mostly on technological solutions, which the corporates are offering governments in particular; it's a very high growth area. So everyone is climbing over each other to get the contracts for government procurement on this. There is undoubtedly an element of this and that's what encourages, in part, the whole idea of locking down the Internet.

There are two types of companies in the world: those that know they've been hacked, and those that don't.

The internet is fracturing into a series of huge country-based intranets, in which governments define, in the name of security, what is legitimate personal and intellectual communication, and what is not.
