8 Sci-Fi Technologies We Should Never Ever Build

Sci-fi has been humanity’s greatest source of inspiration for centuries. Everything the writers thought would be a cool instrument or technology to have in the future was carefully written down and incorporated in various stories. Many of those writers were chemists and scientists of all sorts, so the things they wrote about were not completely impossible. In fact, many of the gadgets and gismos described in books were created a few dozen years later. And with the way technological progress has sped up during the last few years, any unbelievable thing you can think of today can become the reality of tomorrow. Yet there are technologies that are so dangerous that even modern humans won’t be able to contain them. They might be more harmful than helpful. Here are 8 sci-fi technologies we should stay away from.

Nanobot Weapons
Nanotechnology can be as deadly as any other kind of weapon. While it’s a great instrument in terms of healing, growing body parts, organs, and whatnot, nanobots can also be used to wipe out whole cities as there would be literally no cure that would stop this ‘plague of locusts’. One mistake is all it takes to transform the ultimate weapon into a means of world destruction. Self-replicating nanobots are virtually indestructible – they can’t be bombed, shot at, or captured. If they get out of hand – the whole world is doomed.

Self-Replicating Tech
The whole idea isn’t new, not by a long shot. Back in 1948 John von Neumann came up with the idea of a machine that could use raw materials to build a copy of itself and then upload its own programming into the new body (very Matrix-esque if you want our opinion). Of course, creating such a technology would be very beneficial in terms of its cheap production, all you need to do is thoroughly think over the original, and the machine will do the rest of the work. Nevertheless, it’s really dangerous to give control over mass-production of any kind of machine to another machine. So many things could go wrong there! Even if the machines themselves are harmless, when there are too many of them it would cause an immense consumption of resources. Ultimately, the whole world could be taken over by machines!
