Why does the gun have to look all futuristic? Perhaps in 500 years the highest valued things will be perfect replicas of old guns, albeit with more modern internals and better reliability.
After all, who would have guesssed in 1957 that one of the hottest cars in 2003 would be a replica of a '57 T-bird? And how come people today still choose to wear Colt Peacemaker '45’s, which date to the civil war? Patton went through WWII wearing two pearl-handled revolvers, 25 years after the Colt automatic, a much superior weapon, was made the standard service arm.
And there are still people who hunt with bows and arrows, albeit technically advanced ones.
The thing is, guns are easy to work on in a frontier culture, and can pack a surprising amount of energy into a very small space. One person can carry hundreds or even thousands of bullets. They are very effective guns.
This is something I’ve actually been thinking about for quite a while. All of us here grew up during an age of extremely rapid technological advancement, and have come to see it as the norm. Thus, our notion of the future is that it must be some gleaming, high tech utopia like Star Trek.
But curves of advancement flatten out. Look at the automobile: The period from 1900 to 1930 saw such a huge revolution in transportation that ‘futurists’ of the time were predicting skyways and flying cars by 1970. Go look at the ‘world of the future’ from the 1929 world’s fair. It looks like something we would now think of as ‘the future’ in maybe 200 years from now. Our perspective has changed about the future of transportation because the curve flattened out. Cars are certainly better today than they were 50 years ago, but that difference is not NEARLY as significant as the difference between 1952 and 1902.
Or look at light airplanes. The engine in my Grumman AA1 was designed in 1935. The plane itself was designed in 1968, and it’s a MODERN design. There are plenty of private planes flying around that were designed in the 1930’s and 1940’s (The Beech Bonanza, for example).
The B-52 is now scheduled to remain flying until 2050. Do you think the engineers who designed it in the 1950’s would have guessed that it would still be in the U.S. inventory in 100 years?
I find it perfectly plausible that guns like the 1911 Colt could still be in production and being used 500 years from now, barring some unforseen technological revolution.
