"Returning to the notion that exponential growth in the power of computer devices will affect everything else, Kurzweil explained how previously unrelated fields will essentially become information technology fields. For instance, in the field of medicine, an artificial red blood cell called a respirocyte could eventually duplicate the work of the real thing, but with 1,000 times the efficiency.
"Biology is very capable and intricate and clever," Kurzweil said, "but it's also very suboptimal, compared to what we ultimately can build with information technology and nanotechnology...If you were to replace a portion of your blood with these respirocytes, you could do an Olympic sprint for 15 minutes without taking a breath or sit at the bottom of your pool for four hours."
Kurzweil also believes that nanotechnology will solve the world's energy crisis within two decades. Solar panels are hard to manufacture, heavy, inefficient, and expensive, but Kurzweil said the advent of nanoengineered solar panels will change that."
