TED: Vad skulle hända om vi kunde ladda upp våra hjärnor till datorer?

Meet the “ems” — machines that emulate human brains and can think, feel and work just like the brains they’re copied from.

Futurist and social scientist Robin Hanson describes a possible future when ems take over the global economy, running on superfast computers and copying themselves to multitask, leaving humans with only one choice: to retire, forever. Glimpse a strange future as Hanson describes what could happen if robots ruled the earth.

TED: Därför gillar du inte din egen röst

Your voice is indistinguishable from how other people see you, but your relationship with it is far from obvious.

She explains why you may not like the sound of your own voice on recordings, the differences between your outward, inward and inner voices — and the extraordinary things you communicate without being aware of it.
