K. Eric Drexler

Kim Eric Drexler (born April 25, 1955) is an American engineer best known for studies of the potential of molecular nanotechnology (MNT), from the 1970s and 1980s. His 1991 doctoral thesis at Massachusetts Institute of Technology was revised and published as the book ''Nanosystems: Molecular Machinery Manufacturing and Computation'' (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992.

Life and work

K. Eric Drexler was strongly influenced by ideas on limits to growth in the early 1970s. During his first year at Massachusetts Institute of Technology, he sought out someone who was working on extraterrestrial resources. He found Gerard K. O'Neill of Princeton University, a physicist famous for his work on storage rings for particle accelerators and his landmark work on the concepts of space colonization. Drexler participated in NASA summer studies on space colonies in 1975 and 1976. He fabricated metal films a few tens of nanometers thick on a wax support to demonstrate the potentials of high-performance solar sails. He was active in space politics, helping the L5 Society defeat the Moon Treaty in 198

Besides working summers for O'Neill, building mass driver prototypes, Drexler delivered papers at the first three Space Manufacturing conferences at Princeton. The 1977 and 1979 papers were co-authored with Keith Henson, and patents were issued on both subjects, vapor phase fabrication and space radiators.

During the late 1970s, Drexler began to develop ideas about molecular nanotechnology (MNT). In 1979, he encountered Richard Feynman's provocative 1959 talk "There's Plenty of Room at the Bottom." In 1981, Drexler wrote a seminal research article, published by PNAS, "Molecular engineering: An approach to the development of general capabilities for molecular manipulation". This article has continued to be cited, more than 620 times, during the following 35 years.

The term "nano-technology" had been coined by the Tokyo University of Science professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and Drexler unknowingly used a related term in his 1986 book '' Engines of Creation: The Coming Era of Nanotechnology'' to describe what later became known as molecular nanotechnology (MNT). In that book, he proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity. He also first published the term "grey goo" to describe what might happen if a hypothetical self-replicating molecular nanotechnology went out of control. He has subsequently tried to clarify his concerns about out-of-control self-replicators, and make the case that molecular manufacturing does not require such devices.

He is currently a research fellow at the Future of Humanity Institute where his focus is on superintelligence.

Education

Drexler holds three degrees from MIT. He received his B.S. in Interdisciplinary Sciences in 1977 and his M.S. in 1979 in Astro/Aerospace Engineering with a Master's thesis titled "Design of a High Performance Solar Sail System." In 1991, he earned a Ph.D. through the MIT Media Lab (formally, the Media Arts and Sciences Section, School of Architecture and Planning) after the department of electrical engineering and computer science refused to approve Drexler's plan of study.

His Ph.D. work was the first doctoral degree on the topic of molecular nanotechnology and his thesis, "Molecular Machinery and Manufacturing with Applications to Computation," was published (with minor editing) as ''Nanosystems: Molecular Machinery, Manufacturing and Computation'' (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992.

Personal life

Drexler was married to Christine Peterson for 21 years. The marriage ended in 2002.

In 2006, Drexler married Rosa Wang, a former investment banker who works with Ashoka: Innovators for the Public on improving the social capital markets.

Drexler has arranged to be cryonically preserved in the event of legal death.

Reception

Drexler's work on nanotechnology was criticized as naive by Nobel Prize winner Richard Smalley in a 2001 ''Scientific American'' article. Smalley first argued that "fat fingers" made MNT impossible. He later argued that nanomachines would have to resemble chemical enzymes more than Drexler's assemblers and could only work in water. Drexler maintained that both were straw man arguments, and in the case of enzymes, wrote that "Prof. Klibanov wrote in 1994, ' ... using an enzyme in organic solvents eliminates several obstacles ... '" Drexler had difficulty in getting Smalley to respond, but in December 2003, Chemical and Engineering news carried a four-part debate. Ray Kurzweil disputes Smalley's arguments.

The National Academies of Sciences, Engineering, and Medicine, in its 2006 review of the National Nanotechnology Initiative, argues that it is difficult to predict the future capabilities of nanotechnology:

In science fiction

Drexler is mentioned in Neal Stephenson's science fiction novel ''The Diamond Age'' as one of the heroes of a future world where nanotechnology is ubiquitous.

In the science fiction novel '' Newton's Wake'' by Ken MacLeod, a 'drexler' is a nanotech assembler of pretty much anything that can fit in the volume of the particular machine—from socks to starships.

Drexler is also mentioned in the science fiction book ''Decipher'' by Stel Pavlou; his book is mentioned as one of the starting points of nanomachine construction, as well as giving a better understanding of the way carbon 60 was to be applied.

James Rollins references Drexler's ''Engines of Creation'' in his novel ''Excavation'', using his theory of a molecular machine in two sections as a possible explanation for the mysterious "Substance Z" in the story.

Drexler gets a mention in Timothy Leary's '' Design for Dying'' in the "Mutation" section, briefly detailing the 8-circuit model of consciousness (pg. 91).

Drexler is mentioned in DC Comics' ''Doom Patrol'' vol. 2, #57 (published July 1992).

Drexler is mentioned in Michael Crichton's 2002 novel ''Prey'' in the introduction (pg xii).

The Drexler Facility (''ドレクサー機関'') of molecular nanotechnology research in the Japanese eroge visual novels ''Baldr Sky'' is named after him. The "Assemblers" are its key invention.
