Autonomous military robots move from science fiction toward the battlefield in this look inside a United States weapons laboratory. Engineers and scientists working on robotics and artificial intelligence explain what they are building and why, walking through the design and programming choices that let a machine operate without a human at the controls. The film raises the questions that follow naturally from that work: whether a machine can be trusted to make a life-or-death decision, and how militaries and lawmakers might keep pace with technology that is advancing faster than the rules governing it. Interviews with researchers and ethicists sit alongside footage from inside the lab itself, tracing the gap between the Terminator of Hollywood and the slower, more deliberate reality of current military robotics research.
