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.

The Big Idea for Sunday, February 26, 2012

Daniel Dennett, professor of Philosophy at Tufts, sees the brain as a silicon chip inside a head. "We’re robots, made of robots, made of robots, made of robots," he says. But if the brain is a machine, why can't we create machines that are more like people? 

It's isn't easy to face up to the hard problem of consciousness, especially for researchers studying artificial intelligence. For the past forty years, robots have fallen short of humans in their abilities to interact, make use of common sense, and judge the world around them. The process of trying to build a brain has much to teach us about the nature of human consciousness.

Michael Gazzaniga believes that we're still far from understanding and articulating, let alone creating, a convincing model. Physicist Michio Kaku agrees: the current limits of computing power don’t allow a robot to operate with the sophistication to rewire itself or the ability to change it’s structure and function in response to an experience, as the brain can. Sadly, it may be decades before we develop a robot that is as smart as your dog.

As a field, AI tends to focus on thinking, says David Gerlenter, but a brain is much more than thoughts and logic: it also dreams and creates.
