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.

Question: Are we confronting any fundamental limitations in how far science can progress?

Aubrey de Grey: I don’t think there are any inherent failings that are going to hold us back indefinitely. I think it’s purely a matter of progress breeds progress. Progress breeds the expectation of further progress. And it depends on the field. I often make the distinction between fundamental breakthroughs and incremental breakthroughs – incremental refinements of breakthrough if you like. So if you look at pilot in flight, for example, it took us an awful long time to work out how to get bits of … stuff off the ground. But once we’d done it, we were able to refine that rather rapidly. You know, it was only 24 years from the Wright brothers until Lindbergh got across the Atlantic, which the Wright brothers couldn’t have imagined. And of course subsequent progressions. And we can see this in computers. We can see it in the combating of infectious diseases. You name it. So it seems to me that that was because there was no credibility barrier. People tried because they knew that they could make a small advance, and they just did it. It’s big advances that are tricky. But then that also works across fields. If you’ve made big advances in one field, you can make … maybe make it in another field. That’s what I was saying about raising sights. So I feel it’s a psychological thing; but it’s not an intractable, innate, psychological thing. It’s a … a contingent psychological consequence of our … success hitherto.
