James Burke's "Connections" (1979 in the U.S.) is undoubtedly one of the finest educational series ever produced for television, only slightly diminished by his wearing of a (then fashionable) white leisure suit throughout.
No "longtermist" could take their own prognostications about the future a million or 1000 or 10 years from now seriously if they'd ever paid attention to an episode of Connections.
