Doomsday Clock Physicist Warns AI Is Major Threat to Humanity!
Doom Debates!
Comparing AI and Climate Remedies
They contrast geoengineering's potential time horizon with AI's apparent lack of immediate safety tools.
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.
