Here is a short clip of Jack Harper (Tom Cruise) in the movie, battling against killer drones that use artificial intelligence to navigate and hunt 'alien scavengers', and moments before this scene, it was revealed to Harper that alien scavengers were actually humans.

While DARPA's FLA program has yet to mount a directed energy weapon with enough kilowatts to blast a human into smithereens, it seems like the agency responsible for emerging technologies for use by the military has entered into Phase two flight tests — demonstrating advanced algorithms in drones could autonomously perform tasks dangerous for humans — such as pre-mission reconnaissance on the modern battlefield in a hostile urban setting.

..."Unmanned systems equipped with FLA algorithms need no remote pilot, no GPS guidance, no communications link, and no pre-programmed map of the area – the onboard software, lightweight processor, and low-cost sensors do all the work autonomously in real-time."
