VIDEO: AGREE or DISAGREE? Futurist STEWART BRAND Updates His Views on Energy & Geo-Engineering

The man who helped usher in the environmental movement in the 1960s and '70s has been rethinking his positions on cities, nuclear power, genetic modification and geo-engineering. This talk at the US State Department is a foretaste of his major new book, sure to provoke widespread debate.

Why you should listen to him:

Founder of the Whole Earth Catalog, cofounder of the Well and the Long Now Foundation, writer, editor and game designer, Stewart Brand has helped to define the collaborative, data-sharing, forward-thinking world we live in now.

Since the 1960s, he has maintained that — given access to the information we need — humanity can make the world a better place. One of his early accomplishments: helping to persuade NASA to release the first photo of the Earth from space. The iconic Big Blue Marble became the cover for his Whole Earth Catalog, a massive compendium of resources and facts he thought people might like to know. And we did: the 1972 edition sold 1.5 million copies. In 1987, he wrote The Media Lab: Inventing the Future at MIT; in 1994, How Buildings Learn.

Currently Brand is working with computer scientist Danny Hillis to build the Clock of the Long Now, a 10,000-year timepiece; his Long Now Foundation also runs a number of spinoff projects, including the Rosetta Project, cataloguing the world's languages, and the Long Bets website. He's also busy with the Global Business Network (part of the Monitor Group), helping businesses plan for the near and way-far future.
