The Dawn of De-Extinction



Extinct Passenger Pigeons


 Genomics
Throughout humankind's history, we've driven species after species extinct: the passenger pigeon, the Eastern mountain lion, the dodo .... But now, says Stewart Brand, we have the technology (and the biology) to bring back species that humanity wiped out. So -- should we? Which ones? He asks a big question whose answer is closer than you may think.
W ith biotech accelerating four times faster than digital technology, the revival of extinct species is becoming possible. Stewart Brand plans to not only bring species back but restore them to the wild.

Brand, author of Whole Earth Discipline: An Ecopragmatist Manifesto, is already a legend in the tech industry for things he’s created: the Whole Earth Catalog, The WELL, the Global Business Network, the Long Now Foundation, and the notion that “information wants to be free.” Now Brand, a lifelong environmentalist, wants to re-create -- or “de-extinct” -- a few animals that have disappeared from the planet.

Resurrecting the woolly mammoth using ancient DNA may sound like science fiction. However Brand’s Revive and Restore project has an entirely rational goal: to learn what causes extinctions so we can protect currently endangered species, preserve genetic and biological diversity, repair depleted ecosystems, and essentially “undo harm that humans have caused in the past.”

The Story of the Chessboard


The classic parable of how the inventor of the game of chess used his knowledge of exponential growth to trick an emperor is commonly used to explain the staggering and accelerating growth of technology. The 33rd square on the chessboards represents the first step into the second half of the chessboard, where exponential growth takes off.

33rd Square explores technological progress in AI, robotics, genomics, neuroscience, nanotechnology, art, design and the future as humanity encroaches on The Singularity.
