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

Despite calls to relinquish research in nanotechnology, we will have no choice but to confront the challenge of guiding nanotechnology in a constructive direction. Advances in nanotechnology and related advanced technologies are inevitable. Any broad attempt to relinquish nanotechnology will only push it underground, which would interfere with the benefits while actually making the dangers worse.… read more
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
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
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
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
