Science-fiction writers have been trying for decades to prepare us for 2001 and beyond. As more of yesterday's science-fiction comes true, we are forced to believe that some of the far-fetched prophecies being written now will also come true. Not only science-fiction writers like Isaac Asimov and imaginative film-makers like Stanley Kubrick, but professionals in conclaves called Think Tanks, are now busy on what is becoming big business — prediction. Tonight's documentary presents Interwoven patterns of prophecy from all these sources, plus the reactions and visions of those who must come to terms with the 2001 that prophets predict - the children of today who will have to live In it.
