Don't read that trashy WAPO paper Q, that we here in Maryland call it the "Crab Wrapper" along with the Baltimore Sun.

"F8, Facebook revealed it has a team of 60 engineers working on building a brain-computer interface that will let you type with just your mind without invasive implants. The team plans to use optical imaging to scan your brain a hundred times per second to detect you speaking silently in your head, and translate it into text.
Regina Dugan, the head of Facebook’s R&D division Building 8, explained to conference attendees that the goal is to eventually allow people to type at 100 words per minute, 5X faster than typing on a phone, with just your mind.
Eventually, brain-computer interfaces could let people control augmented reality and virtual reality experiences with their mind instead of a screen or controller. Facebook’s CEO and CTO teased these details of this “direct brain interface” technology over the last two days at F8."
