> If you try to extrapolate current tech 50 years into the future, you'll probably get it wrong and people reading your books during the time it's set in will think it quaint. I'm now rereading old SF that I first read 40-to-50 years ago. I don't think I've found a single example where an SF author actually got tech right.
go back a bit further though and you'll get to Arthur c Clarke who accurately predicted geostationary communication satellites
>> An "artificial satellite" at the correct distance from the earth would make one revolution every 24 hours; i.e., it would remain stationary above the same spot and would be within optical range of nearly half the earth's surface.
>> Three repeater stations, 120 degrees apart in the correct orbit, could give television and microwave coverage to the entire planet. I'm afraid this isn't going to be of the slightest use to our post-war planners.
His short story The Sentinel, the precursor to 2001 A Space Odyssey, also has, IIRC, a description of the crew of a lunar rover frying sausages on a hob during one of their missions. And The Deep Range posits mass farming of whales to feed one eighth of the world population. I loved his fiction as a kid but the predictions haven't aged well.
