The public questions of life are often raised by new technologies. In the abortion discussion above, for example, new techniques to end pregnancies, from birth control to abortion procedures, as well as new medical technologies facilitating premature deliveries made the topic more contentious. Other technological innovations also raise questions about life. One such area is that of transhumanism  (c.f. More and Vita-More 2013). Transhumanism is the movement aimed toward the use of technology for the human enhancement of social, psychological, and physical lives. These can range from prosthetics to implants or from pharmaceuticals to mental ‘uploading.’ There are bioconservatives, who argue against transhumanism for practical, moral, or aesthetic reasons. There are also posthumanists, who look forward to a world in which humans are replaced or eliminated by subsequent artificial intelligence. The debate over whether such posthumans might be ‘alive’ is similar in structure to the artificial life discussion in section 3. Bioconservatives also argue against this view. Among the topics in these debates are whether a particular technology counts as therapy or enhancement, whether the risks of alteration outweigh the benefits, whether certain goals of transhumanism are even possible, and which alterations will affect the moral or ontological status of the people that receive them.
