Mankind has been seeking a way to cheat death as long as we have written records. Gilgamesh searched in vain for immortality. Explorers pursued the Fountain of Youth for millennium, some probably died in the process.

Some futurists are now speculating that a form of technological immortality might be right around the corner. They think that a human mind might be “uploaded” onto a computer, as software. The hope is that these “digital people” will retain their identities, memories and personalities, thus serving as an immortal extension of the original person. Is living forever as simple as copying a mind? It depends on how you define a person.
