I'm trying to remember the name of a short film I saw a number of years ago. There was a guy who was a supervisor on an assembly line who's coming near the end of his shift, and he gets a message on his (transparent!) cell phone from his friend, asking if he's going out. The AI (with a female voice) tells him that there's a shortfall in production and that she can get things caught up if he grants her access to the whole assembly line. The guy thinks about it, looking at the message on his phone, and ultimately turns over control. The AI stops making whatever it was (might have been cars) and starts making murderbots instead. The guy goes out onto the production line to see what's going on and gets killed by the machinery. The film ends with the murderbots walking out of the factory into society.
