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: In 40 years, how will we evolve with cooking? 

Richard Wrangham: In modern society the future of food is, if it continues on its present path then we will be eating food that is increasingly highly processed because with every decade the great mills of the industrial food companies are grinding our foods into tinier and tinier particles. So, probably 40 years is too soon, or maybe it's a science fiction future anyway. But I could imagine that there will be a day when our foods will be piped into our houses in some form of algomash that we can then turn into the equivalent of today's hamburgers and donuts. The sort of the basic food that is cheap and very quickly processed. And I suppose exactly how it will happen is unclear, but what you can predict is that the food will become easier and easier to process, more and more processed outside the home, and therefore having fewer and fewer constraints on the domestic economy; on the organization of labor within the home. 

So, in a sense, that's a pessimistic view because it makes food sound uninteresting and maybe the world will be rich enough that it can afford the nice flavors and the interesting textures that the upper classes are able to play with nowadays, that would be nice. But it's also optimistic in the sense that the more that we can move to a world in which the traditional biological constraints on our social relationships are gone, then the more we all participate as equals, and particularly the more we erode the traditional placing of the woman in the home.
