Grey Goo is a theoretical scenario based off of unintended consequenes associated with molecular nanotechnology. The fear is one of growing dependence upon technology that will lead to a technological singularity.
More specifically, is it possible for nanobots, which are theoretically designed for good causes like seeking out cancer cells and destroying them, to self-replicate and mimic something biological like bacteria through recursive self-improvement?
Computers are designed to do only what the programmer functions it to do. However, with the advent of artificial intelligence, machines are designed to problem solve. Being that these machines are now smart and also feed off of biological material, in order to replicate could they consume biological matter?
Is this fear of ecophagy through an evolving artificial intelligence more like science fiction or science fact?
