Can nutritional supplements, biotechnology and nanotechnology help us live forever?
As a skeptic, I am often asked my position on immortality. “I’m for it, of course,” is my wiseacre reply.
Unfortunately, every one of the 100 billion humans who have ever lived has died, so the outlook does not bode well. Unless you follow the trend line generated by Ray Kurzweil and Terry Grossman in Fantastic Voyage: Live Long Enough to Live Forever (Rodale, 2004): “The rate of technical progress is doubling every decade, and the capability (price performance, capacity, and speed) of specific information technologies is doubling every year. Because of this exponential growth, the 21st century will equal 20,000 years of progress at today’s rate of progress.” Within a quarter of a century, the authors say, “nonbiological intelligence will match the range and subtlety of human intelligence,” then “soar past it because of the continuing acceleration of information-based technologies, as well as the ability of machines to instantly share their knowledge.” Biotechnologies, such as designer drugs and genetic engineering, will halt the aging process; nanotechnologies, such as nanorobots, will repair and replace cells, tissues and organs (including brains), reversing the aging process and allowing us to live forever.
