It's fascinating what is unfolding in medicine and other fields with our technology growing, not only expotentially, but the expotential exponent is growing expotentially. Some things you see will happen soon, if not in your lifetime.
- Artificial red blood cells (robotic) carrying 236 X more oxygen, and are imune to virus'.
- Quantum computers that are billions of times faster than todays (built by nanofactories).
- Human organs that repair themselves through gene manipulation (regrowth). Sounds great for gender reasignment.
- Virtual reality will become possible that is every bit as real as actual realilty.
- Within the human body the merging of biology and artifical robotics putting human IQ in the 1000s if not more.
- Life expectancy extension to hundreds of years.

Maybe not in your lifetime but not far away we will be able to program matter. Change any matter into a sofa, or then reprogram it into a Flat TV. Just like the replicators on Star Trek.
We can already make and manipulate artificial atoms and molecules, manipulating their properties therefore the substance. When we have large production of nano-factories the uses will be limited only by our imagination. The nano scale is a thousand times smaller than micro, which is only about 1/80000 of the diameter of a human hair. Or approximately 3 to 6 atoms can fit inside of a nanometer. We alreadly build under the 100 naometer size.
