This was essentially a methodology paper stretched out to 500 pages. Some of their predicted technologies, if rolled up into "a smart phone with wifi access," are surprisingly prescient. Other technologies, especially in medicine, are way off. Politically, their scenarios completely miss the fall of communism and the rise of religious fundamentalism. Their GNP predictions are interesting to look at. If I'm converting from 1965 dollars correctly, the US is at the lower end of their predictions.

Perhaps most depressingly, they predicted an average 27-hour work week (or full time with 4 months of vacation) for Americans by 2000. Here it is, 2015, and if anything work hours are increased for many. ( )

I read this back the 1980's and loved the analysis techniques and tools presented for projecting possible futures. It is very entertaining to read now regarding missed predictions and projections that never happened. You could almost read it's alternate-history content. ( )
