Here is the last part of the same work. Thank you very much, Writeacher.
1) Rather that its utopian promise, Drexler’s book is remembered for the warning that as this technology developed it would be necessary to guard against the accidental release of autonomous self-replicating nano-machines that could turn the planet into a mass of uninhabitable ‘grey goo’.
2) The grey-goo scenario is based on the fear that the self-replicating nanotechnological devices could destroy the natural world.
3) With his vision, Drexler has played an important role in generating both excitement and fear about nanotechnology over the years.
4) But today, there are no current convincing demonstrations to support his future scenery, so many scientists consider infeasible the idea of molecular manufacturing with nanotechnology.
1) In 1986, Eric Drexler published “Engines of Creation”, a scientific dissertation in which not only the theoretical bases of nanotechnology are discussed, but also speculation about the possible consequences of the arrival of a nanotechnology enhanced about the condition of humanity and the planet.
[I have no idea what the underlined part means.]
2) Drexler uses the existence of complex molecular structures present in every living system to show the theoretical possibility of the design and construction of complex structures by means of molecular engineering.
3) He described his vision of a world in which 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.
