NanoTechnology

One weekend in 1993 I read Eric Drexler's book Engines of Creation. I couldn't put it down. I woke up in the middle of the night thinking about the ramifications of this seemingly inevitable technology. Jet engines, houses, food and interstellar spacecraft will be assembled by molecular machines. Instead of ripping iron ore from the Earth, melting it and re-forming it into fasteners and beams and working to connect them all together to build things we will simply provide a set of instructions to these tiny assemblers and watch them create what we need from raw material.

Rather than go into a deep explanation here I recommend just going to the full text of Unbounding the Future here.

One of the greatest implications of this technology is in medicine

Living Forever

Is immortality coming in your lifetime?
I don't know about you, but I have had enough of this cancer thing. It is a software bug. Let's fix it. I don't want immortality, but cancer is an affront to human dignity and must be destroyed. Nanotechnology offers the best solution I can envision. Let's stop treating cancer with brute force and go to the heart of the problem. Imagine swallowing a few pills and having nanobots swimming through your system, calmly comparing DNA sequences to a healthy pattern and fixing the anomalies. Always on patrol these little machines would monitor your entire body for all illness and would eventually make white blood cells obsolete.

The Vasculoid Personal Appliance
Robert A. Freitas Jr. (author, "Nanomedicine") visualizes a future "vasculoid" (vascular-like machine) that would replace human blood with some 500 trillion nanorobots distributed throughout the body’s vasculature as a coating. It could eradicate heart disease, stroke, and other vascular problems; remove parasites, bacteria, viruses, and metastasizing cancer cells to limit the spread of bloodborne disease; move lymphocytes faster to improve immune response; reduce susceptibility to chemical, biochemical, and parasitic poisons; improve physical endurance and stamina; and partially protect from various accidents and other physical harm.
