Editing Life extension (section)

=== Nanotechnology ===
Future advances in [[nanomedicine]] could give rise to life extension through the repair of many processes thought to be responsible for aging. [[K. Eric Drexler]], one of the founders of [[nanotechnology]], postulated [[Cell (biology)|cell]] repair machines, including ones operating within cells and utilizing as yet hypothetical molecular [[computers]], in his 1986 book ''[[Engines of Creation]]''. [[Raymond Kurzweil]], a [[futurist]] and [[transhumanist]], stated in his book ''[[The Singularity Is Near]]'' that he believes that advanced medical [[nanorobotics]] could completely remedy the effects of aging by 2030.<ref>{{Cite book | vauthors = Kurzweil R |author-link=Raymond Kurzweil |year=2005 |title=The Singularity Is Near |publisher=[[Viking Press]] |location=[[New York City]] |isbn=978-0-670-03384-3 |oclc=57201348|title-link=The Singularity Is Near }}{{Page needed|date=September 2010}}</ref> According to [[Richard Feynman]], it was his former graduate student and collaborator [[Albert Hibbs]] who originally suggested to him (circa 1959) the idea of a ''medical'' use for Feynman's theoretical [[nanomachines]] (see [[biological machine]]). Hibbs suggested that certain repair machines might one day be reduced in size to the point that it would, in theory, be possible to (as Feynman put it) "[[Molecular machine#Biological|swallow the doctor]]". The idea was incorporated into Feynman's 1959 essay ''[[There's Plenty of Room at the Bottom]].''<ref>{{cite web |url = http://www.its.caltech.edu/~feynman/plenty.html|title = There's Plenty of Room at the Bottom| vauthors = Feynman RP |date = December 1959 |access-date   = 22 March 2016 |archive-url  = https://web.archive.org/web/20100211190050/http://www.its.caltech.edu/~feynman/plenty.html |archive-date = 2010-02-11 |url-status = dead}}</ref>
