Pope Leo Warns AI and Autonomous Weapons Are Slipping Beyond Human Control
CNBC reported Monday that Pope Leo XIV released his first encyclical, a sweeping 43,000-word document calling on governments worldwide to impose strict AI regulation before the technology outpaces democratic oversight entirely.
Pope Leo Warns of an Unending War Horizon
The document, titled “Magnifica Humanitas” or Magnificent Humanity, argues that AI systems are already amplifying misinformation and embedding a bias toward conflict. Leo warned that this trajectory risked locking humanity into a cycle of perpetual warfare with no clear exit. He called for governments to actively slow down development when market forces are accelerating it. “What is needed is a more active political involvement that is capable of slowing things down when everything is accelerating,” the pope wrote in the text. He demanded robust legal frameworks, independent oversight, and policymakers willing to hold their ground against commercial pressure.
The Autonomous Weapons Problem
Leo raised particular alarm about weapons systems that have advanced to the point where meaningful human control is no longer realistic. He described these systems as having moved practically beyond the reach of any governance mechanism. The pope stated that deploying AI in military contexts must be subject to the most rigorous ethical scrutiny and called it impermissible to delegate lethal decisions to automated systems. He also warned that some leaders might deliberately start conflicts to distract domestic populations from political failures at home.

Background: A Church Rethinking War
Leo’s encyclical broke new ground by explicitly repudiating the just war doctrine, a framework the Catholic Church has applied since at least the fifth century to assess whether armed conflict is morally defensible. That doctrine has been cited recently by US officials, including Vice President JD Vance, to defend American military action in Iran. Leo wrote plainly that the theory has been used too often to justify any war imaginable, and he declared it obsolete. The encyclical also criticized the arms industry directly, arguing that profit motives were a primary driver of global conflicts.

The encyclical’s release was marked by a Vatican event attended by Chris Olah, co-founder of AI company Anthropic. Olah acknowledged that frontier AI laboratories, including his own, operate inside commercial incentive structures that can conflict with responsible development. He welcomed outside scrutiny from institutions like the Church. Leo also called for AI data ownership to be distributed beyond private corporate hands and urged policymakers to protect workers and children from technology’s unchecked reach.
