<p>We&#39;re closer to nuclear catastrophe than at any point since the Cold War.

He explains why he believes humanity has forgotten the lessons of Hiroshima, why today&#39;s rearmament risks repeating the mistakes of history, and how artificial intelligence could make the threat of nuclear war even greater.</p><p>In this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to theoretical physicist and bestselling author Carlo Rovelli about nuclear weapons, the morality of science, AI, international cooperation and why he believes humanity&#39;s greatest enemy is its own irrationality.</p>
