That’s weird to me. I’m from the 1950s and can measure my life in scores of years (three-and-mumble). I was an avid science fiction reader by the 1960s, so recall an era where we wondered if the year 1984, let alone 2001, would be anything like the famous book.
As it turned out, in both cases: No. Respectively fortunate and unfortunate. The future turned out less extreme (but no less “interesting”). Both demonstrate the difficulty of prediction, a problem science fiction illustrates more often than not.
That said, the other face of Janus looks forward…
