I think it's in reference to security. Facial recognition software and ability to access one's pulse temperature breathing pattern their body language these things are starting to be developed for people who have seizures to know that they'll be happening before they start so the person can lay down. Think of like an artificial dog for seizer patients. If you take that technology and perfect it you could put it into any camera system with the right sensors and it might be able to tell you if someone's about to shoot up a place or is thinking about robbing it for harming somebody. The data can be used to preemptively signal an artificial police officer. If one is actually on the scene at the time given its artificial, all the information can be calculated almost instantaneously and imagine someone pulling out a gun and their shot with pinpoint precision before they even get the gun out of it's holster all the way. Now imagine if this system was engaging every single person in the room with that exact precision of understanding and ability to read a scene. It would make a lot less mistakes than a human. Not saying I condone it but I could see that as a possible future scenario
