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

of the greatest implications of this technology is in medicine
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.
Vasculoid Personal Appliance
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
