Merkle, engaged in nanotechnology research at Xerox's Palo Alto Research Center (PARC) with K. Eric Drexler, described the process of molecular manufacturing as one that provides complete control of atoms. He then explained how that, building on John Van Neumann's theories of self-replicating systems (SRS), the manufactured single-molecule unit can replicate into a much larger system. With the use of a slide, he showed how that Drexler's "Architecture for an Assembler," containing a molecular computer, a molecular constructor with "molecular positional capability" and "tip chemistry," is a direct descendant of Van Neumann's design for a self-replicating system, containing a "universal computer" and a "universal constructor." Merkle then went on to relate the development of nanotechnology with the history of computer development, showing charts tracing the increase in power, decrease in thermal consumption and decrease in material necessary to store information. All of the charts show, if the present straight lines remain consistent, that a major milestone will be reached around the year 2015 which is where Merkle sees the "sugar-cube system" arriving. He said, "There's no guarantee that these lines won't either plateau out or have an even steeper acceleration. The lines have been straight for over 40 years, however, and I have no reason to doubt that they will not continue along this line." Merkle then went into the use of these molecular systems in medicine, explaining that we presently have two basic medical tools: surgery, which has intelligent guidance but uses very crude tools that themselves damage the organism, and drugs, which have no intelligence but are atomically precise tools. He said that special purpose molecular computers, no bigger than 1/500 of the width of a human hair, can be introduced into the human system and sent to repair damaged cells. "For the first time we will have adequate tools guided by intelligence. Today, loss of cell function results in deterioration and then death of the cell. In the future, with these tools, the cell can be repaired, providing the structure has not been damaged." Merkle concluded his talk by speculating the impact that molecular machines may have in the field of cryonics. Cryonics is the process of freezing persons whose "death" has been caused by a disease uncorrectable by today's medicine. The theory is that the person will be thawed when there is both a known cure for the disease or injury and a way of repairing any damage caused by the freezing. Merkle said that molecular machines will be the devices that will make such procedures feasible. Merkle said that there is a very simple pay-off matrix for cryonics. "Either you sign up or you don't and it either works or it doesn't. If you sign up and it works, you live. In the other cases you die. If it works, the world in which you awaken will be a world of advanced technology with space travel, space stations and good health." He then showed a slide quoting Apple fellow and former Xerox PARC researcher Alan Kay, saying. "The best way to predict the future is to create it." Alcor Director Brenda Peters told Newsbytes, "We were very gratified at the response to the meeting. The speaker was wonderful and we had many exciting guests. We hope to continue to have as interesting meetings and bring the message of cryonics to more and more people." In response to a Newsbytes question, Peters confirmed that Merkle himself is an Alcor member and said that many engaged in the nanotechnology research have become supporters of cryonics. (Barbara E.
