By the way: its called "SKYNET"
China's SKYNET Surveillance System - Hikvision (deal with Movidius in 2016 for computer vision tech) - Movidius (acquired by Intel in 2016) - Google Project Tango -Movidius partner with google for project tango in 2016

Project Tango -
It uses computer vision to enable mobile devices, such as smartphones and tablets, to detect their position relative to the world around them without using GPS or other external signals.
This is why Apple phones for U.S. agencies?
On 15 December 2017, Google announced that they will be turning down support for Tango on March 1, 2018, in favor of ARCore
ARCore is a software development kit developed by Google that allow for mixed reality applications to be built.
ARCore uses three key technologies to integrate virtual content with the real world as seen through your phone's camera:[1]
Motion tracking allows the phone to understand and track its position relative to the world.
Environmental understanding allows the phone to detect the size and location of flat horizontal surfaces like the ground or a coffee table.
Light estimation allows the phone to estimate the environment's current lighting conditions.
Samsung have announced that ARCore will be used in their product line.
reread…detect their position without using GPS!!!
Deeper research needed on Google's ARCore…it sounds invasive AF!!!
