Alvin Toffler has passed away. The man who introduced us to the concept of future shock. That book was one of those moments when you read something and your whole perspective changes.
It has been argued in some quarters, by the way, the future shock does not exist. I disagree: I think we're all suffering from future shock PTSD at this point.
(Addendum: The New York Times Science/Technology section on carrying on with Toffler's work. The SF Encyclopedia entry on Alvin Toffler.)
(My very worn copy had a green cover, as below. Man, that book went through a lot of printings and updatings!)
