The issue of cyber-security, cyber-crime, and cyber-malfeasance has an impact on a whole range of issues, not the least of which is civil liberties, political activity, and so on and so forth.

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.

The criminal justice system - although this applies less to the U.S., where rehabilitation is not seen as a valuable contribution to criminal justice - in Europe where rehab is supposed to be integral, we have no way of rehabilitating skilled hackers. On the contrary what we do is we demonize them and continue to do so after they come out of jail because we restrict their access to computers by law. Crazy world, crazy people.

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.

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.

I think that we're now deep into a struggle for control over the Internet and there are various actors - state, corporate, civic, criminal and military. The great genius of the Internet is its interconnectedness, but this is also what makes it an incredibly difficult problem when things start to go wrong with it and when people exploit for their own purposes.
