Facebook secretly building technology to read people's minds so they can 'type directly from the brain'

Facebook has revealed its secret "Building 8" where it is crafting technology to read people's minds. As well as its brain-computer interface, the company is working on a wide range of secret projects that use technology in ways never before imagined. Those include special ways of making people sense touch and re-wiring people's brains. The company showed off some of the secretive unit's plans during a speech at its F8 conference. Until now, the team's work has been kept entirely quiet – only leaking out in job ads and other publications.
