Stuart Russell warns of the dangers of developing autonomous weapon systems - arguing for a system of global control. Weapons that locate, select, and engage human targets without human supervision are already available for use in warfare,. Some argue that AI will reduce collateral damage and civilian casualties. Others believe it could kill on a scale not seen since Hiroshima and Nagasaki. Will future wars be fought entirely by machines, or will one side surrender only when its real losses, military or civilian, become unacceptable? Professor Russell will examine the motivation of major powers developing these types of weapons, the morality of creating algorithms that decide to kill humans, and possible ways forward for the international community as it struggles with these questions. Stuart Russell is Professor of Computer Science and founder of the Center for Human-Compatible Artificial Intelligence at the University of California, Berkeley. The lecture and question-and-answer session was recorded at Manchester University. Presenter: Anita Anand Producer: Jim Frank Editor: Hugh Levinson Production Coordinator: Brenda Brown
