Some philosophers, such as Nick Bostrom and the transhumanists, have concocted an updated version of Nietzsche’s superman. Their forecasts are based on two scientific advances presented as imminent since several decades ago: immortality, which will be attained when the advances in medicine increase life expectancy beyond one year per year; and artificial intelligence, the design of super-intelligent machines. Both advances could be combined to attain immortality through artificial intelligence, by downloading our conscience (something we cannot even define scientifically) into a super-intelligent machine, so that it would go on existing inside the machine.
Unfortunately for transhumanists, the UN data do not confirm their expectations. Let us look first at the data about the evolution of the maximum life expectancy in the world from 1950 to 2015 (see table 1). These and the following data have been taken from https://esa.un.org/unpd/wpp/Download/Standard/Mortality/.
