There are bigger questions about whether the technology will create a safer world or usher in a surveillance state. In China, for example, law enforcement officials now rely on facial-recognition glasses to spot and apprehend suspected criminals. The AR system uses lightweight eyeglasses that record images, feed them to the cloud, and, in real-time, provide matches for those engaged in illicit activity. The technology can parse through a database of 10,000 suspects in 100 milliseconds or less. In early 2018, police at Zhengzhou East Railway Station nabbed seven fugitives connected to major criminal cases and identified 26 others attempting to travel using fake IDs, according to People’s Daily, China’s official state newspaper.
