Some futurists believe we are not far from a time when technology and medicine will be so advanced that humans need no longer die of old age or other natural causes. Eventually, not only will we be able to replace our natural body parts, but we might even be able to “download” our selves into a new cybernetic body. But is this a realistic possibility or just a confused fantasy? Is the self the kind of thing that can be downloaded and persist through radical changes in its “hardware”? And if it were possible for people to indefinitely extend their biological lives, what would the moral implications be for social inequality and distribution of the planet’s finite resources?
