There was a real choice when [Barack Obama] became president. It was a very difficult choice - to say, "We're not going to hold senior officials to account with the same laws that every other citizen in the country is held to," or "This is a nation that believes in the rule of law."

That's one of the biggest issues that we see in the question of governments right now, I think, in the Western world. Is that increasingly all of our elected officials are pulled from the same class. These aren't normal people. I don't want to say they're all terrible people, but at the same time, they're not like you and me. These are people who have sort of a nine to five working history.

One journalist said that everybody in Russia is miserable. Russia is a terrible place. And I'm going to end up miserable and I'm going to be a drunk and I'm never going to do anything. I don't drink. I've never been drunk in my life. And they talk about Russia like it's the worst place on earth. Russia's great.

I wonder if it's conservative or liberal [ inalienable rights idea], because when we think of liberal thought, when we think about the relation to liberty, we're talking about traditional conservatism - as opposed to today's conservatism, which no longer represents those views.

If even one country, an Iceland for example, defects from this global legislative bargain and says no, we're not going to enforcement mass surveillance here. We're not going to do that. That's where all of the data centres, all the service providers in the world will relocate to. And I think that gives us a real chance to see a more liberal than authoritarian future.

We've learned that we've allowed technological capabilities to dictate policies and practices, rather than ensuring that our laws and values guide our technological capabilities.

When it comes to political engagement, I'm not a politician - I'm an engineer.
