I really do not know. But something very interesting I can tell you on this. Which has taken place at the thought level at least.

I watched a program (in National Geographic channel) related to “Alien’s visiting planet Earth”. This is a program with data collected from numerous scientific thinkers on this subject with intermediate pep talks given by the eminent scientists working in related fields from various international organizations and universities of high repute.

There they were showing us one possibility that aliens could visit us and destroy us by using their “Self-replicating nanobots”. Now does that sounds great for you? At least our scientists could imagine something wonderful like that, that one day sooner our scientists would be able to have some real self-replicating nanobots roaming our planet!

Quite interesting isn’t it?

I dont think we’ll ever be at a point where we have nano-robots building macro-sized devices such as TVs and cars and such. We already have nano-sized materials that attach to other materials to act as “smart” materials. It is true we’ve just touched the possibilities of nanotechnology, but I still believe nanotechnology will be limited to things such as sunscreen to block UV rays, windshield water blocking, and nanoparticles to make other materials stronger by mixing them into already strong materials such as concrete or steel. We have microelectromechanical systems, which are microstructures capable of sensing and actuating motion. The commercially seen products of MEMS are accelerometers, pressure sensors, and gyroscopes. The fields of MEMS and NEMS still have a long ways to go. It will be an exciting ride.

It all depends on funding. If we put billions into it, we’d have stuff like that in a few years. Right now, it looks as if we’re going to be stuck with nanoscopic zinc-atom IBM logos for a while.
