Since it’s 2015, which is the year that Marty McFly travels forward to in Back to the Future II, it’s gotten me to thinking about all the other SF futures that we’ve caught up with, or have already left behind.
The granddaddy of them all is 1984, of course: when I first read it as a 13 or 14 year old back in 1967 or 1968, 1984 was still a lot further into the future than I could remember into the past. Then we finally got to 1984, and it was just another year.
And there’s 2001: A Space Odyssey and its sequels (one set in 2010, IIRC), and the general cluster of stuff around 2000, which represented The Future for so long (“it’s 2000; where’s my flying car?”)
Another SF touchstone for me has been Joe Haldeman’s The Forever War. His Private Mandella is in basic training in, um, 1997. By 2007, he’s a sergeant, and off on his second engagement with the Taurans, which he doesn’t return from until 2024.
Escape from New York was also set in 1997. Escape from L.A. wasn’t until 2013. 
Much of Ray Bradbury’s The Martian Chronicles was set in 2005.
I’d exclude stuff like Jurassic Park that were set in what was, at the time, the present or very near future. If I were to write a novel set here on Earth as it gets afflicted with a devastating Ebola-like plague in the year 2018, I could just as well be talking about next week.
So what are your favorite futures that we’ve already left behind, or are catching up with?
