I draw a distinction between freedom of the internet and freedom via the internet. In the first case, it's making sure cyberspace is not over regulated and people can say what they want without fear of repercussions. But that's different from this freedom via the internet notion, which is often touted by all sorts of conservatives and neoconservatives who want young people in the Middle East and elsewhere in the world to use Facebook and Twitter and then go oppose their governments.

The reason why there is more pessimism about technology in Europe has to do with history, the use of databases to keep track of people in the camps, ecological disasters.

I have no problem with technological solutions to social problems. The key question for me is, 'Who gets to implement them?' and, 'What kinds of politics of reform do technological solutions smuggle through the back door?'

WikiLeaks is what happens when the entire US government is forced to go through a full-body scanner.

You know, it's not a given that there is an 'online' and 'offline' world out there. When you use the telephone, you don't say that I'm entering some 'telephono-sphere.' You don't say that, and there is no obvious need to say that when you are using a modem.

As Barbara Streisand discovered, adopting a militaristic posture against a tech-savvy mob of civil libertarians is not going to be of much help: Many of them run their own servers and blogs - and have thousands of friends on their social networks - so overzealous attempts to silence them only lead to wider dissemination of sensitive information.

As befits Silicon Valley, 'big data' is mostly big hype, but there is one possibility with genuine potential: that it might one day bring loans - and credit histories - to millions of people who currently lack access to them.
