The author of the breakout hit Here Comes Everybody reveals how new technology is changing us from consumers to collaborators, unleashing a torrent of creative production that will transform our world.
For decades, technology encouraged people to squander their time and intellect as passive consumers. Today, tech has finally caught up with human potential. In Cognitive Surplus , Internet guru Clay Shirky forecasts the thrilling changes we will all enjoy as new digital technology puts our untapped resources of talent and goodwill to use at last.
Since we Americans were suburbanized and educated by the postwar boom, we've had a surfeit of intellect, energy, and time-what Shirky calls a cognitive surplus. But this abundance had little impact on the common good because television consumed the lion's share of it-and we consume TV passively, in isolation from one another. Now, for the first time, people are embracing new media that allow us to pool our efforts at vanishingly low cost. The results of this aggregated effort range from mind expanding-reference tools like Wikipedia-to lifesaving-such as Ushahidi.com, which has allowed Kenyans to sidestep government censorship and report on acts of violence in real time.
Shirky argues persuasively that this cognitive surplus-rather than being some strange new departure from normal behavior-actually returns our society to forms of collaboration that were natural to us up through the early twentieth century. He also charts the vast effects that our cognitive surplus-aided by new technologies-will have on twenty-first-century society, and how we can best exploit those effects. Shirky envisions an era of lower creative quality on average but greater innovation, an increase in transparency in all areas of society, and a dramatic rise in productivity that will transform our civilization.
The potential impact of cognitive surplus is enormous. As Shirky points out, Wikipedia was built out of roughly 1 percent of the man-hours that Americans spend watching TV every year. Wikipedia and other current products of cognitive surplus are only the iceberg's tip. Shirky shows how society and our daily lives will be improved dramatically as we learn to exploit our goodwill and free time like never before.

A revelatory examination of how the wildfirelike spread of new forms of social interaction enabled by technology is changing the way humans form groups and exist within them, with profound long-term economic and social effects-for good and for ill
A handful of kite hobbyists scattered around the world find each other online and collaborate on the most radical improvement in kite design in decades. A midwestern professor of Middle Eastern history starts a blog after 9/11 that becomes essential reading for journalists covering the Iraq war. Activists use the Internet and e-mail to bring offensive comments made by Trent Lott and Don Imus to a wide public and hound them from their positions. A few people find that a world-class online encyclopedia created entirely by volunteers and open for editing by anyone, a wiki, is not an impractical idea. Jihadi groups trade inspiration and instruction and showcase terrorist atrocities to the world, entirely online. A wide group of unrelated people swarms to a Web site about the theft of a cell phone and ultimately goads the New York City police to take action, leading to the culprit's arrest.
With accelerating velocity, our age's new technologies of social networking are evolving, and evolving us, into new groups doing new things in new ways, and old and new groups alike doing the old things better and more easily. You don't have to have a MySpace page to know that the times they are a changin'. Hierarchical structures that exist to manage the work of groups are seeing their raisons d'tre swiftly eroded by the rising technological tide. Business models are being destroyed, transformed, born at dizzying speeds, and the larger social impact is profound.
One of the culture's wisest observers of the transformational power of the new forms of tech-enabled social interaction is Clay Shirky, and Here Comes Everybody is his marvelous reckoning with the ramifications of all this on what we do and who we are. Like Lawrence Lessig on the effect of new technology on regimes of cultural creation, Shirky's assessment of the impact of new technology on the nature and use of groups is marvelously broad minded, lucid, and penetrating; it integrates the views of a number of other thinkers across a broad range of disciplines with his own pioneering work to provide a holistic framework for understanding the opportunities and the threats to the existing order that these new, spontaneous networks of social interaction represent. Wikinomics, yes, but also wikigovernment, wikiculture, wikievery imaginable interest group, including the far from savory. A revolution in social organization has commenced, and Clay Shirky is its brilliant chronicler.
