THE END OF HUMAN CIVILIZATION?

Last weekend, I attended the LibertyCon science fiction convention in Chattanooga and participated in several panels. Once of the most interesting was a discussion of “The End of Civilization.” The panelists (mostly authors and scientists) discussed ways they thought the world -- human civilization -- might end. It was interesting enough to post the initial listing here:

@Michael Z. Williamson “The Yellowstone Supervolcano”

@Tedd Roberts “Drug research run amok”

@Steven Cobb “Asteroid impact”

@Julie Cochrane “A Carrington Event”

@John Ringo “A bioengineered virus”

@Patrick Vanner “Cyber attack”

@Llian Price “Infectious disease”

@Catherine Asaro “The Singularity”

And, finally, my initial contribution “Online virtual reality addiction”

The list grew during the hour-long discussion – what’s your favorite?
