More recently, Joy has made a name for himself as a leading voice warning of the potential dangers of advanced science. In 2000, the same year that the federal government launched the National Nanotechnology Initiative, Joy published an article in Wired magazine that described what he saw as the potential dangers of nanotechnology, genetic engineering, and other advanced technologies. The article, “Why the Future Does Not Need Us,” brought the potential dangers of nanotechnology to a broad audience for the first time. Influenced by the writings of Theodore Kaczynski, the so-called Unabomber, and Eric Drexler’s Engines of Creation, Joy argued that self-replicating nanobots, intelligent robots, and other potential advances in technology might one day prove too difficult for society to safely manage. Terrorists, for example, might design massively destructive biological weapons, while a self-replicating “gray goo” made from nanobots might ravage the earth. As a result of such risks, Joy argued, there are some lines of research that scientists simply should not pursue. Society must, he argued, “limit development of the technologies that are too dangerous by limiting our pursuit of certain kinds of knowledge.” The article was, as one observer put it, “a Cassandra cry about the perils of 21st-century technology and a striking display of ambivalence from a premier technologist.” here
