The New York Times bestselling author of The Everything Store, Brad Stone, takes us deep into the new Silicon Valley. Ten years ago, the idea of getting into a stranger's car or entering a stranger's home would have seemed bizarre and dangerous, but today it is as commonplace as ordering a book online. Uber and Airbnb are well-known names that are redefining neighborhoods, challenging the way governments regulate business, and changing our travel options. In the spirit of iconic Silicon Valley rebels like Steve Jobs and Bill Gates, a new generation of entrepreneurs is sparking another cultural upheaval through technology. They are the upstarts, eccentric founders with boundless drive and a wealth of self-confidence. Young, hungry, and brilliant, they are rewriting the traditional rules of business, transforming our daily lives, and often sidestepping serious ethical and legal objections.
