Well:
The Beach Boys’ song “Kokomo” has nothing to do with the Indiana city, but rather describes a fictional spot in the Florida Keys. (Some maps show Sandals Cay as Kokomo Island, which may have been the song’s inspiration.) However, the owners of a resort and tiki bar on Islamorada Key renamed it to capitalize on the song’s popularity; some reports suggest that one of the Beach Boys knew the bar by that name, and used it for the song. AFAICT, though, it was a case of life consciously imitating art, for publicity.
Heinlein’s technique of extrapolating trends to their logical future outcomes gave him a huge number of prediction “hits”. In addition to “Waldo”, mentioned above, his early short stories include “Let There Be Light”, which focuses on solar power, “The Roads Must Roll,” in which the prediction is made that with greater mobility, the cores of cities would decline as the towns grew towards each other along their interconnections, and “Blowups Haopen,” about the values, dangers, and NIMBY syndrome associated with atomic power – written before any of them were common public knowledge. Other details escape people, though, such as the macho boys wearing earrings in Starship Troopers – thought highly effiminate in 1960 when the story came out, but long since socially acceptable.
Probably Heinlein’s two most interesting predictions, though, were not technological. “Situation Unsatisfactory” shows the U.S. as the sole superpower left in the world, and the universal hatred of the man in control of the U.S. gvernment as a result. An Stranger in a Strange Land, his 1960 tour de force in exploring what happens when 1940s-50s American taboos are broken, has two eerie details: The chief executive who runs the government is guided by his wife, who consults an astrologer for her own advice; and one charactr is made to remark “Whatever happened to Agnew?”
Finally, I think it’s fairly well known that the “Velociraptors” of the movie Jurassic Park were scaled up from the actual genus Velociraptor, which is only the size of a large dog – not adequately menacing for the movie. Shortly after the movie came out, John Horner, the real-life model for paleontologist character Alan Grant, discovered a Velociraptor relative which he named Utahraptor – which matched the movie’s 'raptors to a Tee.
