Life! Don't talk to me about life! Sorry, I shouldn't listen to The Hitchhiker's Guide to the Galaxy while I'm writing this.
When it comes down to it, the way we live our daily lives is what counts. Predictions about the future that deal with spaceships and skyscrapers and nuclear-powered gerbil stretchers are all very interesting, but the predictions that really hit home and that we can judge most accurately are those that deal with how we spend our everyday lives, how we eat, where we live, how we work, and how we play.
Will our living rooms be multi-media lairs, such as shown in the prediction on the left from 1911? Will our house be plastic bubbles? Will we still cook our own food? How will we make a living? What will we do for fun? Why the blazes are we stretching all these gerbils?
