I watched Bladerunner, which I originally saw in a theater in 1982. It's set in 2019, so I wanted to see how it held up, and how close they came to predicting the future. Overall, missed it by a mile.
There were a few conceits, a bunch of 'why the hell not' features of the future. The most obvious was that Los Angeles has become Seattle or Portland and it rains constantly. It's also dark constantly, but maybe everybody just sleeps days. The obvious misses are that we have no fully biological replicated humanoids and no flying cars in our world. That's forgivable. After all, the movie had to be in foreseeable future, just so the cultural references would still mean something. Half of L A was sleek modern buildings and the other half is decrepit mid-20 century derelicts with leaky roofs.
What Blade Runner really missed was the electronics. Besides the easy calls such as the navigational controls in the flying cars, and voice controlled computers(with CRT monitors), they totally missed cell phones. Not a hint. The strangest anachronism in the movie is a newspaper. The hero hides behind a newspaper while tracking down a bad guy(actually a bad gal). There are plenty of crowd scenes, everything from city buses to lunch counters to night clubs. Not a single personal electronic device in sight. No one's face is illuminated by that familiar blue glow.
1982 doesn't seem that long ago. A few years later, my daughter, born in 1983, asked what was new in the world, that wasn't around when I was her age. All I could think of was a microwave oven. I could have added VCRs, but I didn't have one and she'd never seen one. Fast forward and I'm watching Blade Runner from a DVD, on a flatscreen TV.
