I think in general, as a society, we are. Although as other posters have pointed out, our "future" has shrunk from trying to predict the next 100 years to predicting the next 10.
Its better to live with a solid grasp and understanding of the past and evaluate things on that basis, than to exist with a short term memory and perpetual fantasy of the future...
But the latter helps to exploit you more...So I guess that is where the big shot entrepreneurs/corporations/governments want you..
