Science fiction is never about the future, in the same way history is rarely about the past: they're both parable formats for examining or commenting on the present.
It's a great historical joke that when the Spanish met the Aztecs, it was a blind date made in serve-you-right heaven. At the time, they were the two most unpleasant cultures in the entire world, and richly deserved each other.

I walk up a dune to a beach and look out to sea, but it's 100km away. The ships lie askew in their dry beds, at anchor for ever. Today is my son's birthday. Thousands of miles from here, his healthy lungs are blowing out candles. I should be there but I'm here with another boy, who puts his face close to mine and laughs. I smile back but realise he can't see it, because I'm wearing an antiseptic muzzles to protect me from his breath.
