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 way 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?
