It's hard to say if something is a valid prediction without establishing a baseline comparison. It could also be that he's predicting things wouldn't change from the 1960s. > (1) Random acts of violence by crazy individuals, often taking place at schools, plague society in Stand on Zanzibar. In 1966 Charles Joseph Whitman went to a tower on the campus of the University of Texas at Austin and murdered 16 people and wounded 32 others. http://en.wikipedia.org/wiki/List_of_school_shootings_in_the_United_States#1960s http://en.wikipedia.org/wiki/List_of_school_shootings_in_the... lists many acts of violence that took place at schools in the 1960s. In terms of a prediction, the amount of 'random' violence has gone down since the 1960s. > (7) Although some people still get married, many in the younger generation now prefer short-term hookups without long-term commitment. The book was written in the 1960s, in the free love era between effective treatments for VD and AIDS. Compare with the movie "Alice's Restaurant", from the same year as "Stand on Zanzibar", Arlo Guthrie (played by himself) is asked by a teenybopper he just met if he want to have sex with her. He turns her down, ostensibly because he doesn't want to catch her cold. https://www.youtube.com/watch?feature=player_detailpage&v=c0jfwlWDgto#t=1271 https://www.youtube.com/watch?feature=player_detailpage&v=c0... . In terms of a prediction, has the amount of short-term hookups increased since the 1960s? Or stayed the same or decreased? I don't know. But I'm willing to assert that the author of this piece (which was repeated on many sites) doesn't know either. > (10) Motor vehicles increasingly run on electric fuel cells. Really? I thought they increasingly run on batteries, not fuel cells. Wikipedia says: > As of early 2014, there is limited hydrogen infrastructure, with 10 hydrogen fueling stations for automobiles publicly available in the U.S., I haven't read Stand on Zanzibar for a long time and it's not in my collection, so I can't investigate the other claims in any detail.
