EX-DARPA HEAD REGINA DUGAN LEAVES GOOGLE FOR FACEBOOK
Dugan will lead a new team inside the company dubbed Building 8. At Facebook headquarters in Menlo Park, California, each building is tagged with its own number, but there is no Building 8—yet. The name seems to be a play off the aims of the new group: to build all sorts of future technologies for the company. Why 8? There are eight letters in the Facebook name. According to Zuckerberg, the company will put “hundreds of people and hundreds of millions of dollars” in the group, but he did not give a specific time frame for these commitments.

The all-star roster of tech veterans that Facebook began assembling one year ago is quietly making progress, steadily expanding the size of its ranks and the hardware prototypes under development.
The group, known as Building 8, currently has four simultaneous projects underway, spanning everything from cameras and augmented reality to science fiction-like brain scanning technology, Business Insider has learned.
The first such deadline is about a year away, coming up in the summer of 2018. Frank Dellaert, a robotics and computer vision expert, is leading that project.
Additionally, Skydio’s former head of hardware, Stephen McClure, joined Facebook to be Building 8’s head of hardware in January,
Workers from other parts of Facebook have also been pulled in to staff Building 8. One engineer who joined last year named Alex Granieri previously worked on Aquila
Facebook’s early efforts with Building 8 are an indication that the company wants to be a serious player in augmented reality, which is considered to be the next frontier of technology, according to Loup Ventures partner Gene Munster
Still, Building 8 is continuing to make hires from well-known hardware companies. The majority of Building 8’s senior leadership previously worked with Dugan at Google’s advanced technologies division, including the leadership team responsible for the shuttered Project Ara modular smartphone.
