To these recommendations he helpfully adds suggestions for verification of compliance, rounding out complete arms control paradigm for nanotechnologies yet to be invented. Many would argue that it is impossible to develop the good technologies without the bad, and that chance will determine the products of the nanotechnology initiative rather than design. Computers are at the center of this promise. He offers specific criteria for determining which technologies should be allowed and which should not. For example, nonmetal weapons are likely to be more useful to terrorists than to soldiers he advocates that no such weapons be developed.

Wilder ideas include armies of tiny selfreplicating robots that can destroy equipment or fly undetected into building for surveillance. Ethical or legal concerns raised by these devices are largely ignored Altmann is interested only in arms control implications.

Many would argue that it is impossible to develop the good technologies without the bad, and that chance will determine the products of the nanotechnology initiative rather than design.

Coupled with speculative ideas of selfassembly and massive parallelism, many suspect that nanotechnology will dominate new economy governments are scrambling to ensure that they are included in that economy. Altmann judges the list of technologies he has compiled by these criteria. Computers for simulating nuclear weapons tests and codebreaking seem unimaginative next to clothing that provides camouflage in any surroundings, delivers medication to injured body parts, and stiffens to brace broken bones or increase soldiers strength. Altmann gives history of nanotechnology and detailed overview of funding trends, proceeding to exhaustively list and describe potential military applications.

However, the nanoscientists promise has darker side. Speculative systems that integrate small machinery within human body for the purpose of improving memory, reaction time, endurance, or even controlling moods are discussed, but Altmann shies away from tackling questions that quickly become ethical ones.
