If you're a human being on planet Earth right now, chances are pretty good you're reading this from a city. The trend of increased urbanization has been one of the most fascinating demographic trends of the modern age, as increased agricultural productivity and the economic benefits of living close together have combined to bring billions of people from the countryside into the city, often without so much as wiping their feet first. But as more and more time passed, cities graduated from a place people came together to work and trade into a place that looked like home to much of the world's population.

Whatever mankind's future might look like, it seems likely that we will face it together in our glittering, tech-smart urban landscapes.
