On technology. We are wise enough to realize that technology can bring astonishing immediate benefits, but also through unexpected recursive feedback loops, create yet new and unanticipated problems, perhaps as severe as those they were designed to fix. Nevertheless, at the very least microtechnology and nano-technology hold enormous promise for assisting with surveillance tasks to control disease spread. Biobased sensors that can be made cheaply and sensitive down to the individual molecule level promise new ways of scanning large numbers of people (e.g. airport arrivals) cheaply and with minimal intrusiveness. Nano-tech sensors operating within the bodies of suspected infectious persons are also being studied. To see the individual as the broadcasting site for disease surveillance strikes many as a further draconian incursion into the oppression of individual liberty…but to return to our opening theme, this tension between private interest (including the self) and the public's health is endemic.
