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.

John Gray: In respect to many of these technological projects of immortality, what survives is not the person who once lived.  In Kurzweil’s version as a I understand it what is proposed is that elements of the conscious mind, of the conscious self, of the people concerned are somehow programmed, computered and then projected into cyberspace where that self-aware mind can create a variety of bodies for itself in a virtual environment, so rather than having the one frail, aging, vulnerable body that we each of us have to start with people can have a whole variety of different bodies, different genders.  When they get bored with them or want to change them for other reasons they can have as many as they want.  

My objection is that what would survive would not be the person because first of all it would only be the parts of the person which are conscious and can be programmed, and my view is that the larger part of each of us and a large part of where our creativity in our lives comes from, both artistic and intellectual creativity is not conscious.  It’s in part of ourselves which is not accessible to conscious awareness, so if my conscious life, my conscious intellectual life is somehow encoded, encrypted and then projected into a virtual afterlife, what there will be out there will be a poor sort of thinned-out cartoon of the person, a thinned-out image of the whole person I once was, and I'm not interested in that kind of immortality.  I wouldn’t accept it if I were offered it.  

I might very well accept an extension of healthy longevity of the kind that Aubrey de Grey talks about.  We are already living longer and healthier than many previous human generations did.  I see nothing inherently wrong with that, but indefinite longevity is not immortality and it’s not the kind of radical freedom from bodily frailty that futurists such as Kurzweil want.
