Overview
- Pope Leo XIV presented Magnifica Humanitas at the Vatican on Monday, publishing his first encyclical that frames AI as an epochal moral and social challenge and was signed on May 15.
- The text demands robust legal regulation, independent oversight, transparency from developers, and an explicit prohibition on entrusting irreversible, lethal decisions to AI systems.
- Leo urged the 'disarming' of AI to prevent its use as an instrument of domination or war and declared traditional just-war doctrine outdated given autonomous weapons and algorithmic targeting.
- The Vatican hosted Anthropic co-founder Christopher Olah at the launch even though Anthropic is engaged in litigation with the U.S. administration over limits on government use of its technology, a choice that highlights tensions between the Holy See and U.S. policy.
- Beyond military concerns, the encyclical warns AI could deepen inequality and displace workers and includes the first papal apology acknowledging the Holy See’s past role in legitimizing slavery, casting the document as a plea to protect human dignity in the digital age.
