Design of a Primitive Nanofactory

December 4, 2003 by Chris Phoenix

Molecular manufacturing requires more than mechanochemistry. A single nanoscale fabricator cannot build macro-scale products. This paper describes the mechanisms, structures, and processes of a prototypical macro-scale, programmable nanofactory composed of many small fabricators. Power requirements, control of mechanochemistry, reliability in the face of radiation damage, convergent assembly processes and joint mechanisms, and product design are discussed in detail, establishing that the design should be capable of duplicating itself. Nanofactory parameters are derived from plausible fabricator parameters. The pre-design of a nanofactory and many products appears to be within today’s capabilities. Bootstrapping issues are discussed briefly, indicating that nanofactory development might occur quite soon after fabricator development. Given an assembler, a nanofactory appears feasible and worthwhile, and should be accounted for in assembler policy discussions.… read more

The Physical Constants as Biosignature: An anthropic retrodiction of the Selfish Biocosm Hypothesis

February 28, 2006 by James N. Gardner

Two recent discoveries have imparted a renewed sense of urgency to investigations of the anthropic qualities of our cosmos: the value of dark energy density is exceedingly small but not quite zero; and the number of different solutions permitted by M-theory is, in Susskind’s words, “astronomical, measured not in millions or billions but in googles or googleplexes.”… read more

The Transhumanist FAQ

April 30, 2001 by Nick Bostrom

This FAQ, written by Nick Bostrom (with the help of others—see endnote), outlines the principles of transhumanism and provides definitions of transhumanist terms and resources. This is one of many versions of the “Transhumanist FAQ” that can be found on many websites, per organization or individual.… read more

Can a Machine Think?

June 26, 2001 by Clinton W. Kelly

There are three ways to create an AI: model the mind, model the brain, and artificial life. Which one will work?… read more

Jim Lehrer News Hour: Interview with Ray Kurzweil

September 27, 2001 by Jim Lehrer News Hour

David Gergen, editor-at-large of U.S. News and World Report, talks with inventor Ray Kurzweil about his prediction that computers will attain the memory capacity and computing speed of the human brain by around 2020.… read more

If we are lucky, our pets may keep us as pets

January 18, 2002 by Brad Templeton

The first super-intelligent beings may not be based on humans at all, but on apes. Since moral and legal considerations will limit experimentation with human brain uploading, scientists may first turn to apes, and they may quickly enhance themselves. Could they become our overlords, la Planet of the Apes?… read more

Interview with Michael Behar for a story in WIRED on Tactical Mobile Robots

Ray Kurzweil discusses how robots will think on their feet with the help of virtual reality and other technological advances.… read more

National Inventor Hall of Fame Acceptance Remarks

September 22, 2002 by Ray Kurzweil

The National Inventors Hall of Fame (NIHF) inducted Ray Kurzweil on Sept. 21, 2002. Sponsored by the U.S. Patent and Trademark Office and Hewlett-Packard, the ceremony recognized Kurzweil for the Kurzweil Reading Machine and a lifetime of invention, including the first “omni-font” optical character recognition (OCR), the first CCD flat-bed scanner, the first full text-to-speech synthesizer, the first realistic-sounding electronic music synthesizer, and the first commercially marketed large-vocabulary speech recognition.… read more

Lunch with Mikhail Gorbachev

April 19, 2005 by Ray Kurzweil

With only 53,000 engineering graduates a year compared to Russia’s 200,000, the U.S. needs to “communicate the importance of science in today’s world,” Mikhail Gorbachev told Ray Kurzweil in a luncheon discussion that ranged from blogs to nuclear disarmament and longevity.… read more

Nano-Guns, Nano-Germs, and Nano-Steel

March 29, 2006 by Mike Treder

Within our lifetimes, we are likely to witness battles on a scale never before seen. Powered by molecular manufacturing, near-future wars may threaten our freedom, our way of life, and even our survival. Superior military technology allowed the Spanish to conquer the Incan empire in 1532. Could today’s most powerful civilization, the United States, be just as easily conquered by a nano-enabled attacker?… read more

Words and Rules

February 21, 2001 by Steven Pinker

An important problem in AI in understanding how language works. In this paper, presented in his Colin Cherry Memorial Lecture on March 23, 1999 at Imperial College, London, Dr. Steven Pinker suggests that we use a combination of memory and grammatical rules to convey information.… read more

Artificial Intelligence in the World Wide Web

March 7, 2001 by David G. Stork

The Internet is a new metaphor for the human brain. It makes it possible for hundreds of millions of Web users to teach computers common-sense knowledge, similar to SETI@home’s search for E.T., says Dr. David G. Stork, a leading AI researcher. This can even be accomplished just by playing games on the Net.… read more

Consciousness Connects Our Brains to the Fundamental Level of the Universe

May 14, 2001 by Stuart Hameroff

Neurons alone aren’t sufficiently complex to explain consciousness and provide a computational model for thought, according to Stuart Hameroff. He wants to go smaller, into a universe of structures within neurons where quantum mechanics help formulate a physical theory of consciousness.… read more
