On the 78th anniversary of the only wartime use of nuclear weapons, is the human race at another moral crossroads, fearing what artificial intelligence (AI) breakthroughs might unleash? Fei-Fei Li, co-director of Stanford University’s Institute for Human-Centered AI, joins Hoover senior fellows Niall Ferguson, John Cochrane, and H.R. McMaster to discuss AI’s promise and peril, followed by the three “GoodFellows” revisiting Harry Truman’s decision to drop the bombs in 1945. Just as crucial to mankind’s future: they debate the likely winner in an as-yet-unscheduled MMA bout pitting Facebook’s Mark Zuckerberg against X’s Elon Musk.
