Transhumanism is the attempt to artificially improve humans: to enhance their physical and/or mental abilities either by genetic modification, by incorporating technology, or a combination of the two.  The World Economic Forum is vigorously pursuing transhumanism with the goal of creating a better society by actually modifying the individuals.  The idea is that genetically or technologically enhanced humans might have extraordinary athletic abilities, extremely high intelligence, resistance to disease, and lengthened lifespans.  Is such a goal possible?  If so, is it something that we should pursue?  What are the scientific and moral implications?
