I think Chinese leadership is trying to tell the world they have another set of logic or reasoning or values which are different from yours. Of course, I don't think they believe that. It's just an argument that's made when you can't confront the truth and facts. They really want to maintain power.

The 'Bird's Nest' National Stadium, which I helped to conceive, is designed to embody the Olympic spirit of 'fair competition.' It tells people that freedom is possible but needs fairness, courage and strength.

The Olympic Games are highly commercialised. They purport to follow the traditions of an ancient athletics competition, but today it is the commercial aspect that is most apparent. I have seen how, through sport, cities and corporations compete against each other for financial gain.

To survive, China had to open up to the West. It could not survive otherwise. This was after many millions have died of hunger in a country that was like North Korea is today. Once we became part of global competition, we had to agree to some rules. It's painful, but we had to. Otherwise there was no way to survive.

What I'm concerned about are two things. I think one that John Miller talked about, and that's the radicalization over the Internet that ISIS is very adept at doing. The other one is a foreign fighter threat.

We have an obligation to figure out how to help people cope with the rapidly changing nature of technology.

Mozilla has one foot in the Valley, Silicon Valley product technology, and partly one foot in the social enterprise space.

There used to be rather serious firewalls between the artist and the buying public - the gallery, the publisher. And technology demolishes that wall and basically says, 'Self-promote or die.' And that is a bad head for any sort of artist to be forced into.
