Today, for the first time - and the Obama campaign showed us this - we can go from the digital world, from the self-organizing power of networks, to the physical one.

We have this condition where digital technology is becoming increasingly smaller and distributed in the environment. In a certain sense, this is the first time ever we can describe a city in real time.

My muse is the digital world.

As people talk, text and browse, telecommunication networks are capturing urban flows in real time and crystallizing them as Google's traffic congestion maps.

This digital world is completely fascinating to me.

I grew up in a physical world, and I speak English. The next generation is growing up in a digital world, and they speak social.
