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.

Interfacing Your Brain with Computers

April 17, 2011, 9:36 AM

What's the Most Recent Development?

Renowned scientist and professor of neurology at Brown University, John Donoghue has made incredible advances in interfacing the human brain with computers, allowing paralyzed people to move objects by simply using their imagination. A small chip implanted in the brain picks up the right neural signals and beams them into a computer where they are translated into moving a cursor or controlling a computer keyboard. "By this means, paralysed people can move a robot arm or drive their own wheelchair, just by thinking about it."

What's the Big Idea?

The implications of a brain-computer interface are formidable, from transferring human consciousness onto a computer—in other words, immortality—to using the technology to read people's minds. Military establishments are interested in Dr. Donoghue's research in order to enhance interrogations methods. Were interrogators able to interface the mind of a prisoner with a computer, perhaps information could be extracted they could use to prevent criminal acts and save lives. It seems the next phase of evolution will be synthetic, rather than purely biological.
