As science and technology advance, we see a growing public concern about their social and cultural consequences. There are fears about whether future developments in robotics, genetic engineering, and nanotechnology, for example, will enhance the welfare of humankind or prove to be a Faustian bargain. Such fears are causing a technological backlash, especially in developed nations. The science and technology communities must engage in these discussions, be completely open to listening to such concerns, and assess and address them. If we do not listen and respond, we will lose the public as partners.
