AI Catastrophe

Accelerating artificial intelligence progress, outpacing safety research and governance amid geopolitical competition, is the most probable route to human extinction. A 2026 Lancet Commission identified malicious AI use—such as designing biological weapons—and nuclear conflict as the sole threats with extinction potential this century, judging climate breakdown a greater risk only in later centuries.
