The descriptions of the new London- a roofed city of skyscrapers, largely lacking in private space- are exhilarating. Among the things Wells predicted and got approximately right are these: television, video, surveillance cameras, sexual equality, porn, celebrity hairdressers, powered flight, motorways, moving walkways, fascism and the Battle of Britain. Things he failed to anticipate include mass migration and the future's distaste for unthinking racism.
He later said he thought this particular future was impossible because capitalists aren't smart enough to become despots. Living in a age in which the gap between rich and poor continues to widen and only millionaires can aspire to high office I'm not so sure.
