The Foresight Guidelines (Foresight Inst.i.tute, version 4.0, October 2004, http://www.foresight.org/guidelines/current.html) are designed to address the potential positive and negative consequences of nanotechnology. They are intended to inform citizens, companies, and governments, and provide specific guidelines to responsibly develop nanotechnology-based molecular manufacturing. The Foresight Guidelines were initially developed at the Inst.i.tute Workshop on Molecular Nanotechnology Research Policy Guidelines, sponsored by the inst.i.tute and the Inst.i.tute for Molecular Manufacturing (IMM), February 1921, 1999. Partic.i.p.ants included James Bennett, Greg Burch, K.

Martine Rothblatt, CEO of United Therapeutics, has proposed replacing this moratorium with a regulatory regime in which a new International Xenotransplantation Authority inspects and approves pathogen-free herds of genetically engineered pigs as acceptable sources of xenografts. Rothblatt's solution also helps stamp out rogue xenograft surgeons by promising each country that joins the DCA, and helps to enforce the rules within its borders, a fair share of the pathogenfree xenografts for its own citizens suffering from organ failure.

2. 2. In the function In the function y y = 1/ = 1/x, if x x = 0, then the function is literally undefined, but we can show that the value of = 0, then the function is literally undefined, but we can show that the value of y y exceeds any finite number. We can transform exceeds any finite number. We can transform y y = 1/ = 1/x into into x x = 1/ = 1/y by flipping the nominator and denominator of both sides of the equation. So if we set y to a large finite number, then we can see that by flipping the nominator and denominator of both sides of the equation. So if we set y to a large finite number, then we can see that x x becomes very small but not zero, no matter how big becomes very small but not zero, no matter how big y y gets. So the value of gets. So the value of y y in in y y = 1/ = 1/x can be seen to exceed any finite value for can be seen to exceed any finite value for y y if if x x = 0. Another way to express this is that we can exceed any possible finite value of = 0. Another way to express this is that we can exceed any possible finite value of y y by setting by setting x x to be greater than 0 but smaller than 1 divided by that value. to be greater than 0 but smaller than 1 divided by that value.
3. 3. With estimates of 10 With estimates of 1016 cps for functional simulation of the human brain (see chapter 3) and about 10 cps for functional simulation of the human brain (see chapter 3) and about 1010 (under ten billion) human brains, that's 10 (under ten billion) human brains, that's 1026 cps for all biological human brains. So 10 cps for all biological human brains. So 1090 cps exceeds this by a factor of 10 cps exceeds this by a factor of 1064. If we use the more conservative figure of 1019 cps, which I estimated was necessary to simulate each nonlinearity in each neuron component (dendrite, axon, and so on), we get a factor of 10 cps, which I estimated was necessary to simulate each nonlinearity in each neuron component (dendrite, axon, and so on), we get a factor of 1061. A trillion trillion trillion trillion trillion is 1060.
