Back to 20,000 A.D. by Nat Schachner (w. AL Zagat):
Science Fiction Inventions, Technology and Ideas

"TO those readers who read “In 20,000 A.D.” the present sequel must be very welcome for it not only carries on the great adventures of that fateful time of the distant future but also introduces newer and more amazing experiences.

When we look back over the history of the human race, say for the past 18,000 years, and then project it ahead for 18,000 years more we can get a good index of the unbelievable changes that will occur to us before the year 20,000.

We know that the tendency is for the race to become more and more intellectual and less emotional; and for it to consciously rather than unconsciously evolve, as we control our environment more and more. Arthur Brisbane once said that the man of the future will be a cold calculating chess player who will be almost all brain and little body; and he will have to be carried around on air cushions to avoid even the most delicate of shocks to his nervous system. Our authors go several steps further than Mr. Brisbane in their prophecies and give us pictures of a future world that are almost unmatched for their imaginativeness!" Select an invention:
