The Age of Em: Work, Love and Life when Robots Rule the Earth is a 2016 nonfiction book by Robin Hanson.

[1] 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 next era is likely to arise from artificial intelligence in the form of brain emulations, sometime in the next century or so.

He commended the book for bringing a social science perspective, for the detail it gives, and for providing a starting point for further study.

He also criticized some of the book's arguments and stated that different authors would reach different conclusions about the same topic.
