When you look at a city, you know, it looks so unique. You feel this kind of uniqueness, you know, and especially if you go from a big city to a small city or if you go from one country to another. Cities look very different, often. They even feel very different. You know, and they are, of course. They certainly are.

You could not have evolved a complex system like a city or an organism - with an enormous number of components - without the emergence of laws that constrain their behavior in order for them to be resilient.

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

Geoffrey West Quotes
