This is some funny stuff. Orson Welles hams it up narrating this anti-progress scare documentary. There are all sorts of bizarre extrapolations of future technological and sociological trends from what people were thinking about at the time (1972), from mass polyamory and perpetual youth vagabonds to genetically-engineered flower children. If only he knew how much less fun the future would be...
What is most entertaining and unintentionally hilarious is the fact that though it purports to predict the future, its production values and techniques are as rooted in the early '70s as you can get - with everything from bad lighting, creepy Moog synthesizer music, and plastic robot costumes, to cheap special effects courtesy of the McGraw-Hill educational filmstrip conglomerate of the time. That period was itself such an abberration that it was probably the worst possible period to use for meaningful predictions. Now, if Welles had said in his narration, "One day, you will be able to watch this film on a small personal computer along with any other film you choose," I might have had some respect.
