“Magnifica Humanitas:” Pope Leo’s Clarion Call on AI

Since stepping into the Papacy, Pope Leo XIV has been a forceful voice pushing back against the anti-human path we’re on with AI. In May, he released “Magnifica Humanitas,” a sprawling encyclical warning of the dangers to human dignity and agency posed by runaway AI. Tristan had the incredible opportunity to meet with the Pope ahead of the encyclical's release. 

In the modern world, you’d think we would have developed governance structures to deal with powerful new technologies like AI. It's worth asking why a 2,000-year-old religious institution is the only one standing up and loudly declaring that the default path is unacceptable. 

In this episode, Tristan and Aza discuss what it was like for Tristan to be at the Vatican, why this is such a critical step toward a pro-human future, and how we can build on the momentum of the Pope’s call to action.

Corrections:

  • Tristan said that Pope John XXIII gave his radio address weeks after the Cuban Missile Crisis. It actually occured during the crisis. 

  • Tristan paraphrased the full quote from Pope Leo's encyclical on AI disarmament. Here is the full quote: "Disarming AI means freeing it from the mentality of “armed” competition, which today is not limited simply to the military context, but is also an economic and cognitive phenomenon. This entails a race for ever more powerful algorithms and larger datasets, driven by the desire to secure geopolitical or commercial dominance."

  • Aza slightly misquoted Dr. King Jr. The full quote begins "The means by which we live have outdistanced the ends for which we live."

  • The delegates for Bretton Woods came from just 44 countries, not "hundreds" as Tristan said.
