The latest enthusiasm for eternal life largely stems not from any acid-soaked, tie-dyed counterculture but from the belief that technology will enhance humans and make them immortal. Today’s transhumanist movement, sometimes called H+, encompasses a broad range of issues and diversity of belief, but the notion of immortality—or, more correctly, amortality—is the central tenet. Transhumanists believe that technology will inevitably eliminate aging or disease as causes of death and instead turn death into the result of an accidental or voluntary physical intervention.
