"From a social point of view most SF has been incredibly regressive and unimaginative. All those Galactic Empires, taken straight from the British Empire of 1880. All those planets — with 80 trillion miles between them! — conceived of as warring nation-states, or as colonies to be exploited, or to be nudged by the benevolent Imperium of Earth towards self-development — the White Man’s Burden all over again. The Rotary Club on Alpha Centauri, that’s the size of it."
