In 1964, Calder, who was then editor of New Scientist, asked 100 experts their predictions for 20 years hence. In 1984, he evaluated the results and looked forward another 20 years. Some things he did point out as concerns like global warming and sustainable development are prescient. He also correctly noted the demographic transition. Of course, this was definitely a product of its time. AI and fusion are still nowhere on the horizon. This may also have been the last book written to take seriously that automation would put us out of work. Nothing like the Internet is mentioned. (Connections between computers are small computers to the central big computer.) The main prediction, this being the 80s, is nuclear war. It only took 5 years for history to diverge from the path described here. ( )
