Re: Chicken Little is Still Alive and Squawking . . .
Actually I agree with Eric Drexler's Foresight Institute's concern about potential mis-use of nanotek. I would not characterize that appropriate level of concern and advanced planning as being Chicken Little syndrome. I would consider blind Luddite opposition to nanotek R&D as chicken little. Or the instance where Bill Joy woke up one day and went "Holy S----! Nanotek & AI could be dangerous!"
