That will be coming down the pike soon my friend. Ever heard of "nanobots"? They are the smallest creations of humans yet. Nano means (one billionith of a meter), meaning that it would take 1 billion nanometers to make one meter, which is about 3.8ft. That is extremely small if you didn't catch that. This will allow for pico scale technology (we are currently at Nanometer technology on microchips (now called nanochips) The nanobots won't only be used in computer technology, but in Health and Life Sciences, as well as engineering fields.
Imagine this: You are sick one day, with the evil Flu virus. You go to the doctor, and he says, ok, hang on one sec. Now normally, you would expect him to give you some directions like drink lots of fluids, stay in bed, and keep warm and take these pills to keep down your nausea. But with nanobots, he says here ya go, here is a shot, give it about 3 hours or so, then you will be fine...
Why? The nanobots will be in the shot, and when he injects them into your bloodstream, the nanobots will begin to devour and seek and destroy all of the Flu virus particles, and any infected cells. Then they will go on, and it will take about 30 years for them die. All that time, they are cleaning up blood clots, stopping cancer from forming, helping out your cells, etc. Wierd eh?
Here is a fact: Scientists are almost done with the Blastoplast, a new nanorobot that is an artifical red blood cell with 1,200X the capacity of a normal red blood cell. This means that you could:
1). sit at the bottom of a pool for 3 hours
2). Sprint at full speed for 15minutes and not get tired or out of breath.
This is kinda spooky, so I will leave this subject alone, but this is going to happen (within the next 20 years). Be ready, because you think PCs are fast now, give it 10 years.
