1) In 1986, Eric Drexler published “Engines of Creation”, a scientific dissemination in which shows not only the theoretical bases of nanotechnology, but also a series of speculation about the possible consequences of the arrival of a nanotechnology enhanced about the condition of humanity and the planet.
2) The existence of complex molecular structures present in every living system is used by Drexler to show the theoretical possibility of the design and construction of equally or more complex structures with means of molecular engineering.
3) He described his vision of a world where molecular manufacturing would allow people to manufacture anything they might need simply by feeding waste material into a box that would use nanoscale assemblers to re-configure it into the necessary form.
