![]() Drexler says arms control is a far greater issue than gray goo "nanobugs". In less than a day, they would weigh a ton in less than two days, they would outweigh the Earth in another four hours, they would exceed the mass of the Sun and all the planets combined - if the bottle of chemicals hadn't run dry long before.Īccording to Drexler, the term was popularized by an article in science fiction magazine Omni, which also popularized the term "nanotechnology" in the same issue. At the end of ten hours, there are not thirty-six new replicators, but over 68 billion. ![]() Imagine such a replicator floating in a bottle of chemicals, making copies of itself.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, and the eight build another eight. In Chapter 4, Engines Of Abundance, Drexler illustrates both exponential growth and inherent limits (not gray goo) by describing " dry" nanomachines that can function only if given special raw materials: Eric Drexler in Engines of Creation (1986). The term was first used by molecular nanotechnology pioneer K. In 2004, he stated "I wish I had never used the term 'gray goo'." Engines of Creation mentions "gray goo" as a thought experiment in two paragraphs and a note, while the popularized idea of gray goo was first publicized in a mass-circulation magazine, Omni, in November 1986. Eric Drexler in his 1986 book Engines of Creation. The term gray goo was coined by nanotechnology pioneer K. ![]() Self-replicating machines of the macroscopic variety were originally described by mathematician John von Neumann, and are sometimes referred to as von Neumann machines or clanking replicators. The original idea assumed machines were designed to have this capability, while popularizations have assumed that machines might somehow gain this capability by accident. ![]() Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass on Earth while building many more of themselves, a scenario that has been called ecophagy (the literal consumption of the ecosystem). ![]()
