Pope Leo XIV today issued a landmark call to "disarm" artificial intelligence, framing it as an existential threat to humanity in his first encyclical, *Magnifica Humanitas*. The 80-page document, presented at the Vatican alongside Anthropic co-founder Chris Olah, warns that unchecked AI risks deepening global conflicts, normalizing warfare, and creating "new digital slaveries" through geopolitical and corporate dominance.
The encyclical demands strict regulation of AI development, urging governments and tech giants to dismantle systems capable of autonomous decision-making in military or surveillance contexts. "AI must be disarmed before it disarms us," the Pope declared, comparing the technology’s societal impact to the Industrial Revolution’s upheavals. He specifically criticized "the race for ever more powerful algorithms," driven by "the desire to secure geopolitical or commercial dominance," as reported by *Le Monde* .
Key themes of *Magnifica Humanitas* include:
The encyclical marks Leo XIV’s most assertive intervention in global policy since his 2025 election, leveraging the Vatican’s moral authority to pressure institutions like the UN and EU to adopt binding AI treaties. While the document stops short of endorsing a full ban, it aligns with growing calls for a "digital Geneva Convention" to prohibit lethal autonomous weapons. Observers note the timing—amid stalled AI regulation talks in Brussels and Washington—positions the Pope as a pivotal mediator in the debate.
*Magnifica Humanitas* is the first encyclical by a U.S.-born pontiff and reflects Leo XIV’s background as a former missionary in Latin America, where he witnessed technology’s uneven impacts. The Vatican has announced plans to host a summit later this year, inviting policymakers, ethicists, and AI researchers to draft concrete proposals for "disarmament." As *France 24* reported, the Pope’s message is clear: "Humanity’s survival may hinge on whether we choose to control AI—or let it control us" .
