There are people in the world who do not understand how anyone could love classic science fiction. That declare they have no relevance. I ask in turn: what’s not to love? Heaps of books shouting to the heavens: “WELCOME TO THE DISTANT YEAR TWO THOUSAND OT FIFTEEN; MAN HAS CHARTED THE UNIVERSE (PROBABLY SOMETHING TO DO WITH WHY THE UNIVERSE IS ALSO IN CHAOS), AND ALSO FLYING CARS.” Should damn well put a bloody tear in your eye to see the high hopes our forefathers once had for us.
As for relevance, well, maybe you have a point there…I mean, of course, you had classics like Metropolis that let us all know by the year 2000 we would be living in a highly stratified class system where the poor are brutally oppressed and worked to death as living machines. Thank God that didn’t happen, right?
