In April 2016, the 12th, during the annual developer’s and engineering conference “F8”, Mark Zuckemberg announced a new project on “building new hardware products to advance our mission of connecting the world” that will be infused with “hundreds of people and hundreds of millions of dollars”.
Similar to Google’s X division and Amazon’s Lab126, the name of such project is Building 8. Even if that building wasn’t exist yet, the day after, April the 13th, it was announced that the former head of Google ATAP, yet former director of DARPA, Regina Douglas had the lead of Building 8. 
“I’m excited to have Regina apply DARPA-style breakthrough development at the intersection of science and products to our mission,” Zuck wrote in a post. “This method is characterized by aggressive, fixed timelines, extensive use of partnerships with universities, small and large businesses, and clear objectives for shipping products at scale.” 
In fact, on December 2016, the 21st, on a FB post Regina announced a collaboration with 17 Universities under the “Sponsored Academic Research Agreement”. 
On Jannuary 2017, the 13th RT News reveled the DARPA’s strategic interest in FB. Thanks to the partnership with the U.S. military FB will benefit of a new “almost magic” technology to be monetized on the virgin market, a technology that DARPA want to be delivered to the masses, using this gigantic IT corporation. 
The spooky news was reposted by many newspapers on-line and in fact at the F8 conference Regina Dougan herself took a speech and announced Facebook is working on other ways to hear, within the project Building 8. One example of Building 8’s work so far, Dugan said, was an attempt to improve technology that allows people to type words using their minds.
“It sounds impossible, but it’s closer than you may realize,” Dugan said.

Regina Douglas knows what she is talking about. At the beginning of 2008, it was already possible to detect thoughts of familiar objects, by the use of mind scanners in conjunctions with a computer’s algorithm. The thought of specific objects have been mapped to specific brain activation patterns by a group of researcher at the Carnegie Mellon University, Pittsburgh, Unites States. 
The Intel Lab at Pittsburg is part of Intel Research division, that was created in 2000, under the leadership of David L. Tennenhouse. Tennenhouse aimed to model his new research organization based on DARPA, where he had previously been director of the Information Technology Office. 
In 2010 the DARPA’s budget for the fiscal year included $4 million to start up a program called Silent Talk. The goal was to “allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals”. 
Before being vocalized, speech exists as word-specific neural signals in the mind. 
DARPA wants to develop technology that would detect these signals of “pre-speech,” analyze them, and then transmit the statement to an intended interlocutor.
