Robots may one day rule the world, but what is a robot-ruled Earth like? Many think that the first truly smart robots will be brain emulations or "ems." Robin Hanson draws on decades of expertise in economics, physics, and computer science to paint a detailed picture of this next great era in human (and machine) evolution - the age of em.
"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."
Unfortunately it seems both Hanson and qntm have been proven incorrect. Our overlords will be bootstrapped from reddit and wikipedia rather than scanned brains.
You might enjoy reading The Age of Em. Imagine in 90 years you could literally spin up a copy of the em who wrote the code that's having issues, archived at a time with context full in mind, have them fix the issues or add some new related features, then spin them down again, with most funds probably going to the general clan of related ems.
It's still an interesting read a few years later but it definitely needs a follow up.
