It's great that the Internet can enhance and speed up our communications and that computers can do all the things they do. It's fabulous. At the same time, it changes our priorities. For example, before I would always remember people's telephone numbers and now I don't know anyone's number. So what happens if computer systems go down but you still have landlines? Well, I couldn't call anyone because I don't know anyone's number.

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.

If there is an event for whatever reason, which interferes with the Internet or network communications, are people able to deal with it? It seems like our dependency on these systems is so great that the room for maneuver as it were is very small. So that is problematic.

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 anonymity issue is a big question. As long as people can disguise cyber attacks and as long as there is a sort of question mark over who is responsible, then the problem will continue to exist. And of course what happens in response to that is that there is a move to try and refashion the Internet so that anonymity is impossible, which of course leads to fears among all sorts of groups - civil rights groups, NGOs, and political parties - that the Internet is going to be used simply as a method of control. So these are very sensitive issues.

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.
