The Age of Em
The Age of Em: Work, Love and Life when Robots Rule the Earth is a 2016 nonfiction book by Robin Hanson.
Summary
The book explores the implications of a future world in which researchers have not created artificial general intelligence but have learned to copy humans onto computers, creating "ems," or emulated people, who quickly come to outnumber the real ones.The book's main scenario proposes that in about a hundred years from now, human brains will be scanned at "fine enough spatial and chemical resolution," and combined with rough models of signal-processing functions of brain cells, "to create a cell-by-cell dynamically executable model of the full brain in artificial hardware, a model whose signal input-output behavior is usefully close to that of the original brain."
