A June 29, 2006 Slate piece by Reihan Salam reflects on futurism and had some fascinating insights. An excerpt appears below.
Even so, it's not fair to say that all futurism is misguided. Just most of it. In his 1976 Time essay "Is There Any Future in Futurism?" Stefan Kanfer wrote that you could divide futurists into neo-Malthusians and Cornucopians. Neo-Malthusians are convinced that the world is going to hell. Some, like The Population Bomb's Paul Ehrlich, blamed population growth; others, like the Club of Rome, blamed economic growth. Either way, the prescription remained the same: You've got to change your evil ways, Earthlings.
