Beyond Human: How Cutting-Edge Science Is Extending Our Lives

Herold (Stem Cell Wars) looks at the effects of converging technologies in genetics, computing, nanotechnology, and engineering on the length and quality of the human lifespan. Extrapolating from current innovations under development, the author posits that effectively eliminating disease and aging-related death will revolutionize future conceptions of work, family, and society. Taking these scientific advancements as inevitable, she advocates that we should be discussing these ethical and philosophical questions now to inform practical and policy implications because of the rapid advance of these technical fields. While attempting a balanced presentation of arguments, she ultimately sides with the transhumanists who favor biological modification against bioconservatives that call for a moratorium on life-extending enhancements. Important topics investigated include artificial organs, aging as a disease, and whether the line between medical treatment and biological enhancement matters. A chapter on robotics feels a bit out of place but extends the discussion of how artificial intelligence will alter human interaction.
