City Tech

The world is rapidly urbanizing, and experts predict that up to 80 percent of the population will live in cities by 2050.

In this thoughtful, inquisitive collection, Rob Walker-former New York Times columnist and author of the City Tech column for Land Lines magazine-investigates the new technologies afoot and their implications for planners, policymakers, residents, and the virtual and literal landscapes of the cities we call home.
