What a world run by virtual humans will be like

Robin Hanson gives a Ted talk

Economist Robin Hanson is the latest to weigh in on the thorny questions accompanying the future of AI, but approaches it with the tools of a macroeconomist to describe how emulated human brains—or as he calls them, "ems"—will interact with us in the economy of the future.

What Hanson predicts: In a recent Ted Talk, Hanson argues that in a world in which we have figured out how to recreate the human brain using computers, human labor will instantaneously become obsolete, because "they just can't compete" with artificial brains that will be as capable as the most intelligent humans (though not more so, as Hanson is not theorizing about the so-called "singularity" when artificial intelligence becomes super-human).
