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.

Why True AI Sits on a Far Distant Shore

What's the Latest Development?

In his new book, How to Create a Mind, engineer and futurist Ray Kurzweil puts forth a theory of the brain that is meant to demonstrate how engineers could build a computer that would mimic the mind closely enough to achieve consciousness. The key, says Kurzweil, is pattern recognition. If a computer can be made to recognize patternsfrom letters that make words to faces in the cloudsit would be, in essence, a human mind. Kurzweil's detractors argue that his understanding of cognition is far too simplistic. Patter recognition applies to perception but not to abstract thought, which is far different and much more complex.

What's the Big Idea?

Beyond the specifics of Kurzweil's theory are the words used to describe it. He is certainly not alone in his description of neurons as things that "send signals", which allow the brain to "process information". Sending and processing, however, are activities done by conscious minds. The brain, strictly speaking, engages in certain chemical and electrical activities that are causally connected to genuine informational activities (these are taken up by the mind). Metaphors for how the brain works are too often presented as knowledge about the brain itself. Presently, our understanding of the brain remains theoretical.
