What is Grey Goo? Not necessarily grey, and not necessarily gooey, “grey goo” is both a nanotechnological substance which increases exponentially without practical limit, and a hypothetical scenario in which the mass of planet Earth – or the universe – is ecotophaged into self-replicating nanobots. Mathematician John von Neumann originally described macroscopic self-replicating robots. These replicators are sometimes called “von Neumann machines.” In turn, nanotechnology pioneer Eric Drexler coined the term “grey goo” in his book Engines of Creation. Drexler described the exponential growth and inherent limits of such highly specialized nanomachines: “…the first replicator assembles a copy in one thousand seconds, the two replicators then build two more in the next thousand seconds, the four build another four . . in less than two days, they would outweigh the Earth; in another four hours, they would exceed the mass [...]

Imagine a world in which there are no limits on the human lifespan, no restrictions on our capacity for intelligent thought and exponential technological advancement, no barriers to our saturating the universe with consciousness. Imagine all the people, living for forever. Indeed, John Lennon might have gotten a kick out of imagining himself casually interfacing with artificial intelligence, nano-engineering solar panels in space, breathing molecularly cleansed air through bionic lungs…but if this is a reality you want to see, you’ll have to “live long enough to live forever”, as Terry Grossman and Ray Kurzweil claim in their book of the same title. What Grossman – the main subject of the forthcoming documentary The Methuselah Generation: The Science of Living Forever - means by this is bolstering your longevity enough to be able to utilize the tools and treatments of the biotechnological revolution. From there you will need survive [...]
