Doomsday Clock Physicist Warns AI Is Major Threat to Humanity!
About this episode
Renowned scientists just set The Doomsday Clock closer than ever to midnight.
I agree our collective doom seems imminent, but why do the clocksetters point to climate change—not rogue AI—as an existential threat?
UChicago Professor Daniel Holz, a top physicist who sets the Doomsday Clock, joins me to debate society’s top existential risks.
