Facebook is developing mind-reading technology

Facebook is turning its attention to "silent speech communications", working on a system that will let people type words on a computer using only their brains.
The company made the announcement during the last day of its annual F8 conference on Wednesday (19 April), and was quick to assuage users of what the project means for their privacy. 
60 engineers are currently working on the technology from clandestine Building 8 - Facebook's innovative product research and development hub.&nbs
