This article presents arguments from both position pros and cons, about technological incorporations in human bodies. The denaturalization of technologically enhanced humans is discussed; A discussion is raised about the impact of these technologies on the population inequality; We present a contrast between whether the research is for treatment or enhancement purposes. Some of the repercussions on a society (...) of humans are analyzed, both hyper connected and technologically enhanced. Some of the future challenges that societies with technologically enhanced humans must face are presented. In conclusion, the development of technologies, within a regulatory and normative framework, to enhancing the characteristics and capacities of human beings is ethical. Because technologically enhanced humans are part of the NBIC convergence, and the NBIC convergence will generate new knowledge that will surely be used to develop clean and safe energy sources, preventive medical treatments that will eliminate diseases such as cancer and HIV, and design strategies to the conservation and decontamination of the planet.
