The Internet obviously changes things; we've seen that in the music industry above all else. As an author, I'm now having to deal with the fact that it's happening in the publishing industry as well. And publishing is going through a very difficult time. Some view it as positive, some negative, but nobody really knows how to deal with it. If you're an author it looks very challenging because your work can be pirated so easily and there's very little you can do about it.

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.

Clearly there are some things about WikiLeaks... the material is in part very interesting although none of it is a real game-changer. I think if I was an American I'd be rather proud that American diplomats are quite assiduous in the way that they chronicle issues. Of course the impact has been that the whole culture of sharing is going down the tube.

There are governments who are regulating things in different ways and those forms of regulation often don't square up. So you have a real legislative mess, in the meanwhile various bad people are developing all sorts of tools to exploit the Internet for their own gain and the militaries are beginning to develop some extremely frightening offensive capabilities in cyber. Yet all of this is taking place outside of any international agreement or even framework.

When you're researching things that have happened, the clear narrative arc is not there already. This is the problem of writing nonfiction for me - writing nonfiction which is about serious subjects and has serious political and social points to make, yet which is meant to be popular to a degree - what happens when the facts don't fit a convenient narrative arc? I guess that for a lot of nonfiction writers that is a central challenge.

The U.S. has the most advanced cyber-weaponry on the planet, and t if you look at the U.S. from the perspective of the Chinese People's Liberation Army, which runs most of its cyber activities, they look at you and they see Google and Facebook - the two largest depositories of personal data in the world - and they see the reach of the National Security Agency, which has huge digital capacity to know what is going on around the world. So the Chinese would see cyber as an un-level playing field, because the U.S. holds all sorts of advantages.

The Internet has fashioned a new and complicated environment for an age-old dilemma that pits the demands of security against the desire for freedom.
