As media evolve, Shirky asks, what sort of arguments will we have — and how will it change the governments of nations?

Clay Shirky is an adjunct professor in New York Universityʼs graduate Interactive Telecommunications Program, where he teaches a course named Social Weather. He's the author of several books, including his most recent, Cognitive Surplus: How Technology Makes Consumers into Collaborators.
Shirky's work focuses on the rise of networks and the use of decentralized technologies for social creation and open-source development. "A group is its own worst enemy," he says; new technologies can enable cooperative structures as alternatives to centralized and institutional structures.
