There are many academics, including Einstein, who held the opinion that imagination is the motor that drives invention, although necessity may be the fuel that powers that motor.
Therefore, science fiction, which is a sector that relies wholly upon imagination, and as such can be seen to be a driver for invention, is the precursor for new gadgetry. Think of Star Trek in the 60’s when we had hand-held communication devices that showed the person’s face, and of course, automatic doors.
The following list gives us a light-hearted look at the science fact that has sprung from science fiction. It is not complete by any means, but does help us to see how the script writers can be harbingers of things to come. Expect a terminator to kill you any day now.
