Radicals are not going to disappear. They're going to go underground. They're going to be hardened. And they're not going to be exposed to contrary ideas made by educated people who can make real, convincing, and persuasive arguments to deradicalise these people.

US has to be able to rely on a safe and interconnected internet in order to compete with other countries.

The way the United States intelligence community operates is it doesn't limit itself to the protection of the homeland. It doesn't limit itself to countering terrorist threats, countering nuclear proliferation. It's also used for economic espionage, for political spying to gain some knowledge of what other countries are doing.

Every time somebody on the internet sort of glances at us sideways, we launch an attack at them. That's not going to work out for us long term, and the U.S. have to get ahead of the problem if we're going to succeed.

I'm not a politician, and I do not think I am as effective in this way as people who actually prepare for it - is to focus on technical reform, because I speak the language of technology. I spoke with Tim Berners-Lee, the guy who invented the World Wide Web. We agree on the necessity for this generation to create what he calls the Magna Carta for the Internet. We want to say what "digital rights" should be. What values should we be protecting, and how do we assert them.

In the United States the White House has appointed two different independent panels who had full access to classified information for the last 10 years that master balance has been in place in the United States, and they found that despite intercepting the calls - everybody in the country, - it had never stopped a single terrorist attack. So the question is, why would these officials be pursuing these policies, if we know they don't work, if they don't stop terrorism?

I do not want to live in a world where everything I do and say is recorded. That is not something I am willing to support or live under.
