Project Maven, a Department of Defense program launched in April 2017 to apply AI in military targeting and logistics, is now being used in live combat. Katrina Manson is a reporter and the author of Project Maven: A Marine Colonel, His Team, and the Dawn of AI Warfare, a book just published by W.W. Norton & Company that tells the history of the program. Justin Hendrix spoke to her about the book and about recent events, including the use of AI targeting in the war in Iran and the battle between the Pentagon and Anthropic over 'red lines' such as the use of AI for lethal autonomous weapons.
