The Dangers of Nanotech

Krees writes "Small Times talked with the Foresight Institute's Christine Peterson, Ralph Merkle of Zyvex, and Ray McLaughlin of Carbon Nanotechnologies about the potential of nanotechnology, which has benefited greatly from open source research methods, and nanotech weapons in particular falling into the wrong hands. Recent recognition of potential abuses will likely lead to incrased secrecy in nanotech research." This topic comes up every so often - what happens when nanotech falls into the wrong hands? I think that's a "when", not an "if", as that happens with almost everything.

Foresight guidelines and related stuff

[WillWare]

The Foresight Institute (with which Drexler and Peterson are associated) has come up with a set of development and design guidelines for nanotech. These would go far to prevent most accidents, but they depend on developers to self-police, as has happened in the area of genetic engineering. Regrettably they don't prevent acts of terrorism.

The commonly cited "gray goo" scenario is a sort of nanotech worst case: nanites that can convert almost any naturally occurring matter (including biomatter) into more identical nanites. Robert Freitas has done some analysis concluding that gray goo would either work very slowly, or throw off a huge amount of heat which could be detected by a thermal monitoring system of geosynchronous satellites. Drexler has observed that making a gray goo nanite is likely to be an enormous engineering challenge.

These kinds of topics pop up on sci.nanotech with some frequency. Here are some discussions: November 1996, March 1997, September/October 1997. My own thinking is that we want to ensure that the development of defensive measures outpaces the development of offensive weapons. A step in the right direction would be for the good guys to maintain a development/design/simulation effort that clearly outpaces anything the bad guys can do. (This obviously sidesteps the issue of who gets to define "good guys" and "bad guys", and whether the good guys become corruptible given a commanding technological lead.)
