Support of Transhumanists appearance and the convergence of technologies such as the nanotechnology, biotechnology, the information technology and cognitive science (NBIC), and future hypothetical technologies such as simulated reality, the artificial intelligence, the superb intelligence, the downloading spirit, and the cryonics. They believe that the human ones can and should employ these technologies to become more than the human one. They thus support the identification and/or the protection of cognitive freedom, morphological freedom, and procreative freedom as civil freedoms, in order to guarantee individuals the choice to employ human technologies of improvement on themselves and their children. Some speculate that human enhancement techniques and other emerging technologies may facilitate more radical human enhancement by the midpoint of the 21st century.
A report/ratio 2002, convergent technologies to improve the human execution, commissioned by the National Science Foundation and ministry for the trade of the USA, contains descriptions and comments on the state of the science of NBIC and technology by contributing principal to these fields. The report/ratio discusses the potential uses of these technologies while putting pursuant to the goals of transhumanist of execution and health increased, and continuous work on applications envisaged of human technologies of improvement in the soldiers and the rationalization of the man-machine interface in industry. While the international discussion of convergent technologies and the concepts of NBIC includes the strong criticism of their fictitious nature of orientation of transhumanist and pled science, research on technologies of change of brain and body accelerated under the patronage of the department of the USA of the defense, which is interested by the advantages of battle field that they would provide to the supersoldiers of the United States and his allies.
