I have read dozens of books and seen at least that many movies that attempt to envision the future. Most miss the mark wildly. Of those which don't, they usually only get one or two things right, like Jules Verne predicting the submarine, or Star Trek showing the "communicator," long before every person on earth had his/her own cell phone.
The rest of the "predictions" in these movies or books usually completely miss the mark, like the Star Trek transporter, as one example.
The worst record for inaccuracy, however, usually goes to those who attempt to specifically predict the future, rather than just showing some idea as a plot device. I was alive at the time this film was made, and many people were predicting flying cars (like we saw ten years later in "The Jetsons."). Chester Gould kept predicting flying ships that used antigravity to stay in the air.
By contrast, this show accurately predicts videotape, three years before Ampex brought the first successful video recorder to market (the 2" Quadruplex broadcast tape recorder in 1958). It shows home video recording twenty years before it happened with the first Betamax. We see home videophones over thirty years before Skype (and later, Facetime) brought it to the masses.
It correctly predicts the microwave oven which also didn't happen for another twenty years, in the early 1970s.
They even showed a woman in a kitchen getting her recipes from a video card catalog, very much like many people cook using recipes they display on their tablet or phone.
One segment shows what amounts to an early MIDI sequencer, a forerunner of the MOOG synthesizer and Melotron both of which didn't happen until the late 1960s.
Some of the things are just happening now, like their prediction of remote surgeries, where the doctor and patient are separated by thousands of miles.
Even small things, like the prediction that we'd have ice dispensers that would dispense both cubes and crushed ice is something I didn't see in homes until the early 1970s.
Most amazing to me -- and it is worth seeing just for this one segment -- is its statement that "many scientists" believe that the future of energy production is direct energy from the sun via solar cells. This is mind blowing given that this was the heyday for nuclear power, and much of the last part of the short describes all the wonders of the atom. I didn't think the silicon solar cell was invented for another five years, but they show a small prototype generating enough energy to move the needle on a galvanometer.
Some of the prediction are less stunning, but in light of the other things they got right, they add to the film's credibility. These include the prediction that the just-invented transistor would help miniaturize electronics, and that the computer would improve manufacturing precision and productivity.
They didn't get much wrong, although since this was the "atomic age," the movie does go a little overboard in predicting that we'd all embrace things like irradiated food. This did happen, and it is perfectly safe, but people got spooked because of all the scare B-movies about monsters created by radiation from the atomic bomb.
I really enjoyed this short and highly recommend it to anyone wanting to see the rare movie that somehow is able to correctly see and predict the future.
