We form cities in order to enhance interaction, to facilitate growth, wealth creation, ideas, innovation, but in so doing, we create, from a physicist's viewpoint, entropy. ”

Cities tolerate crazy people. Companies don't. ”

It's hard to kill a city, but easy to kill a company. ”

Cities are the origins of global warming, impact on the environment, health, pollution, disease, finance, economies, energy are all problems that are confronted by having cities. That's where they - all these problems come from. ”

On average, an individual doesn't have a powerful connection with more than four to six people, and that's just as true here in the U.S. as it is in China. ”

Sometimes, I look out at nature and I think, 'Everything here is obeying my conjecture.' It's a wonderfully narcissistic feeling. ”

A human being at rest runs on 90 watts. That's how much power you need just to lie down. And if you're a hunter-gatherer and you live in the Amazon, you'll need about 250 watts. That's how much energy it takes to run about and find food. ”

Slums could be thought of as the development of a special organ, or they could be thought of as a tumor that's grown, and in some ways is unhealthy and could ultimately lead to the city's destruction. My own feeling is that slums are probably a bit of both. ”

One of the remarkable things about slums is that they do develop their own social organization and economy and even culture that is, on some level, functional and in some cases, remarkably resilient. This is kind of amazing. ”

Once we started to urbanize, we put ourselves on this treadmill. We traded away stability for growth. And growth requires change. ”
