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.

Robotic evolution

Robot_visions As New Scientist Tech points out, it will soon be possible to "evolve" colonies of robots that are able to think, act and even pass on their robotic DNA to future generations:

"Robots that artificially evolve ways to communicate with one another have been demonstrated by Swiss researchers. The experiments suggest that simulated evolution could be a useful tool for those designing of swarms of robots. Roboticists Dario Floreano, Sara Mitri, and Stéphane Magnenat at the Swiss Federal Institute of Technology in Lausanne collaborated with biologist Laurent Keller from the University of Lausanne.

They first evolved colonies of robots in software then tested different strategies on real bots. Both simulated and real robots were set loose in an arena containing two types of objects – one classified as "food" and another designated "poison" – both lit up red. Each bot had a built-in attraction to food and aversion to poison. They also have a randomly-generated set of parameters, dubbed "genomes" that define the way they move, process sensory information, and how they flash their own blue lights... Their "genomes" were combined and randomized in a way designed to mimic mating and mutation and used this to create the next generation robot."

With a nod to Charles Darwin, the Swiss researchers are calling the process by which "smart" robots live and "dumb" robots die "unnatural selection."
