Stephen Euin Cobb is today's featured guest. (This is an experimental episode in which the questions normally posed to others, I direct at myself.)Topics: My opinion that the earth needs a thermostat. That the days in which the temperature of the earth can be left to nature need to come to a close. And that if the fear of global warming gets people motivated enough to pay for an engineering project large enough to regulate the earths temperature on a day-to-day basis then that fear will have served humanity well.Also described are: scenarios which might produce the fall of civilization; how the singularity might go well or go badly; and why I believe I have a 50 percent chance of living for hundreds of years, although not in my current physical form or with my current personality.Hosted by Stephen Euin Cobb, this is the April 29, 2009 episode of The Future And You.
