This is the homepage for Robin Hanson's book 'The Age of Em,' which explores a speculative future where brain emulations (ems) dominate the economy. It is relevant to AI safety as it examines long-term consequences of advanced AI/emulation technology on society, values, and human welfare.

Summary

The Age of Em by Robin Hanson is a book that uses standard social and physical science theories to describe a detailed, plausible future dominated by brain emulations—digital copies of human minds running on computers. It explores how ems would work, live, and organize society, projecting rapid economic growth and radical social change. The book challenges assumptions about moral progress by showing how descendants may hold very different values due to adaptation rather than ethical advancement.

Key Points

  • Brain emulations (ems) are posited as the first truly smart robots: scanned human brains run as software on fast computers.
  • Ems could displace humans in most jobs and cause the world economy to double every few weeks.
  • The book applies physics, economics, and social science to rigorously extrapolate what an em-dominated world would look like.
  • Em society challenges human moral assumptions, as ems may reject many values humans currently hold dear.
  • Author Robin Hanson is an economist at George Mason University and research associate at Oxford's Future of Humanity Institute.

 Robots may one day rule the world , but what is a robot-ruled Earth like?

 Many think the first truly smart robots will be brain emulations or ems .
Scan a human brain, then run a model with the same connections on a fast computer,
and you have a robot brain, but recognizably human.

 Train an em to do some job and copy it a million times:
an army of workers is at your disposal.
When they can be made cheaply, within perhaps a century,
ems will displace humans in most jobs.
In this new economic era, the world economy may double in size every few weeks.

 Some say we can't know the future,
especially following such a disruptive new technology,
but Professor Robin Hanson sets out to prove them wrong.
Applying decades of expertise in physics, computer science, and economics,
he uses standard theories to paint a detailed picture of a world dominated by ems.

 While human lives don't change greatly in the em era,
em lives are as different from ours as our lives are from those of our farmer and forager ancestors.
Ems make us question common assumptions of moral progress,
because they reject many of the values we hold dear.

 Read about em mind speeds, body sizes, job training and career paths,
energy use and cooling infrastructure, virtual reality, aging and retirement,
death and immortality, security, wealth inequality, religion, teleportation, identity, cities,
politics, law, war, status, friendship and love.

 This book shows you just how strange your descendants may be,
though ems are no stranger than we would appear to our ancestors.
To most ems, it seems good to be an em.
