What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Humans Still Rule Computers at the Game of Go

What's the Latest?

For the all the hullabaloo that accompanied Deep Blue's famous triumph over Russian chess grandmaster Gary Kasparov, there remains a strategy game at which humans remain undefeated. The reason is that Go is a vastly more complex game than chess. In chess, Black and White have twenty possible moves each. After the opening moves, there are 400 possible board positions. In Go, Black and White begin with 361 possible moves, and after the opening exchange there are 129,960 possible board positions. The rate at which available moves increase is called a game's "branching factor." Chess’s branching factor is 35. Go’s is 250. 

What's the Big Idea?

Experts predict that computer dominance in Go remains at least 10 years out, mostly because the moves of top professionals become far less predictable as the game progresses. Still, even once a computer does defeat a human player, human intelligence will still reign as such. "In fact, computers can’t 'win' at anything," argues Wired's Alan Levinovitz, "not until they can experience real joy in victory and sadness in defeat, a programming challenge that makes Go look like tic-tac-toe. Computer Go matches aren’t the brain’s last stand. Rather, they help show just how far machines have to go before achieving something akin to true human intelligence."
