They could be a Curse

Nanotechnology holds great promise and problems in the future. When applied to medicine, nanobots could repair the body internally, attack diseases, do surgery, and protect the body from attack. Nanobots could make the body better and allow those that can’t function normally to live normal or above-normal lives.

There are some problems though. If nanobots interact with the body wrong, they could be deadly. If they need to defend themselves from the immune system, the immune system could be compromised. Also, if the nanobots are programmed to enhance the body, it could become overenhanced. It might be fun to be able to run 100 mph and fly like Superman. But the amount of energy required would make a person need to eat almost constantly. And if not all the body is adjusted for enhancement, there could be damage and possible death.

Nanotechnology could produce a superior brain with enhanced abilities like telepathy, mind control, telekinesis, total body control and override ability, super abilities, and more mental storage capacity. They would have to be similar to existing brain cells so they don’t require as much energy or else they might burn the brain out. Einstein would seem like an idiot compared to a nanobot-enhanced brain. But the enhancement could drive some people insane or cause them to act more like an emotionless machine. Cyborgs are part robot and part human. So you could say nanobots could make people into cyborgs. But will they act human or like a terminator?

Nanobots will at times be able to replicate. This is important when it comes to the construction of a massive amount of microscopic things or material made from microscopic things. When super-tough, super-light material needs to be made like the cables for cable-tension suspension bridges that might have cable filaments longer in total than the sun to the Oort Cloud, billions or trillions of nanobots will be needed. They might even build the bridges that will stretch for miles between supports. They would take the materials needed and construct the bridges so quickly that the bridge across the Long Island Sound between Long Island and outside Rye, New York might be completed nearly overnight. But unless the construction nanobots are used for more bridge or building construction projects like the construction of stratotowers that will be miles tall, the nanobots may have to be disposed of, which would be a waste of material. With the need of infrastructure rebuilding around the world, a trillion nanobots may be employed all the time.

Food production will be helped by nanobots, too. Synthetic food could be produced by them to relieve hunger around the world. If a typhoon hits India or somewhere else in Asia and crops are destroyed, nanobots may need to produce emergency synthetic food. It might be best to use automated ships and planes to bring the food in because if the nanobots run out of raw material to produce food from, a crew might be the best available material to turn into food.

Nanobot catalysts might be able to turn organic material into fuel or maybe use the energy fields that surround us to provide electricity. They could act like bacteria. But if they are released into nature, they might attack living organisms like fish or birds and turn them into energy. That is why nanobots need to be controlled to prevent disasters in nature. If all goes right, they could be a blessing. If handled wrong or go out of control, they could be a curse.
