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.

Upmanu Lall: I think our entire story is about technology.  Can technology now get us out of the sustainability jam?  In the 1960 to 1980 period there was the Club of Rome that kept talking about, what is the population the world can support? And going further back it was, you know, Malthus in the 18th, 19th century time period.  Let’s think about that, okay?  What we saw as estimates of what the world can support itself that were made between 1960 and 1980 ranged from one billion people to one trillion people, so obviously we had no clue.  The fact that we are at seven billion and, in many respects, metrics for human standards of living have improved globally - if you normalize it on the number of people we have, we have surprisingly good standards of living today than what we had before - so if you recognize that, where did that come from?  And it has come simply because we have been able to develop technologies that do two things: one is they allow us to extract much more of the resources that we need out of the planet at a much lower cost.  This is not necessarily good because it points to exhaustion and collapse.  So many people today will argue that this is a temporary blessing.  We are out of shape after some time.  But the second thing technology has allowed us to do is to recycle and reuse many things and also to improve the efficiency with which some of the things that we have extracted from the planet can be used, and this efficiency comes in multiple ways - getting more energy out of the same block of things, getting more agriculture productivity out of the same thing of water or we use the same resource multiple times - what is the waste of one process is then used as the input into the next process.

Maybe the best way to rephrase that technology question is, what are the most important technologies that we should be focused on today that guarantee us sustainability as a planet through this century with the idea that as overall education and affluence improves we will reduce fertility rates and bring the population under balance so we don’t have an exploding threat of population consuming no matter what we do with the current technology.
