Pope Leo XIV Calls for AI Disarmament to Protect Workers and Humanity

Context On May 25, the Vatican unveiled *Magnifica Humanitas*, Pope Leo XIV’s inaugural encyclical. The 42,300‑word document confronts the rapid spread of artificial intelligence, echoing the social‑justice focus of Pope Leo XIII’s 1891 *Rerum novarum* on industrial workers. A short film preceding the address linked past technological leaps—from the printing press to smartphones—to the escalating ease of autonomous weapon deployment.

Key Facts - The pope states AI must be "disarmed" to prevent domination of humanity. He clarifies disarmament means regulation, not abandonment of the technology. - He calls for the creation of regulatory tools that uphold justice and curb the distorting effects of technological power. - Leo XIV draws a parallel with nuclear disarmament, insisting both AI and nuclear capabilities should serve the common good, not become weapons. - The encyclical warns that autonomous weapons make war more feasible and less subject to human control, rendering traditional "just war" theory outdated. - The Vatican invited Christopher Olah, co‑founder of AI firm Anthropic, marking the first non‑clerical speaker at such a papal event. Olah echoed the pope’s call, urging participation from professionals beyond computer science to shape AI governance.

What It Means Leo XIV’s appeal adds moral weight to ongoing policy debates in the United States, Europe and Asia over AI safety and military use. By framing regulation as a moral imperative rather than a technical fix, the Vatican may influence legislators to adopt stricter oversight mechanisms, similar to those governing nuclear arms. The inclusion of industry leaders suggests a willingness to collaborate across sectors, potentially accelerating the development of international standards for AI transparency and accountability. Watch for upcoming UN discussions on AI arms control and any formal Vatican‑backed proposals for a global regulatory framework.
