Danny Hillis: The Internet could crash. We need a Plan B

February 27, 2013


In the 1970s and 1980s, a generous spirit suffused the Internet, whose users were few and far between. But today, the net is ubiquitous, connecting billions of people, machines and essential pieces of infrastructure -- leaving us vulnerable to cyber-attack or meltdown. Internet pioneer Danny Hillis argues that the Internet wasn't designed for this kind of scale, and sounds a clarion call for us to develop a Plan B: a parallel system to fall back on if -- or when -- the Internet crashes.

Dan Pallotta: The way we think about charity is dead wrong

March 1, 2013

In this bold talk, he says: Let's change the way we think about changing the world.

February 28, 2013


“Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk.

James B. Glattfelder: Who controls the world?

October 25, 2012


James Glattfelder studies complexity: how an interconnected system -- say, a swarm of birds -- is more than the sum of its parts. And complexity theory, it turns out, can reveal a lot about how the economy works. Glattfelder shares a groundbreaking study of how control flows through the global economy, and how concentration of power in the hands of a shockingly small number leaves us all vulnerable.
