21.   Imagine a world in which doctors are able to manipulate human behavior the way we manipulate broken bones today.

22.   Imagine a world where man was too busy with war to reach the stars.

23.   Imagine a world where the carbonated drinks have gone flat, the sandwich-makings are like cardboard, and the air hangs like week-old tobacco smoke.

24.   If we imagined a nightmare world, it might be a place governed by illiterate teen-age boys.

25.   Imagine a world in which companies issue their own cash.

26.   Imagine a world in which you do not have to remember passwords or worry about them falling into the wrong hands.

27.   Imagine a world not too far in the future, where voice-activated computers are installed in kitchens everywhere.

28.   Imagine a world where true e-cash is an everyday reality.

29.   Imagine a world without ATM cards and personal identification numbers, where the human body serves as the ultimate ID.

30.   It is difficult to imagine a world in which there is nothing left to wonder about.
