Pope Leo XIV urges UN to ‘disarm’ AI, warns machines are tools not persons

Pope Leo XIV used his Friday address to urge United Nations member states to adopt concrete measures aimed at restricting the most autonomous forms of artificial intelligence, describing the effort as a "disarmament" of machines that should remain tools rather than decision‑makers.

The 87‑year‑old pontiff framed the issue in moral terms, asserting that humanity bears the responsibility to guide, reshape, or, when necessary, reject the deployment of AI systems that could overstep ethical boundaries. He reminded listeners that the Church has long cautioned against technologies that undermine human dignity, linking the current debate to earlier papal statements on biotechnology and digital privacy.

In the speech, Leo called for a coordinated international approach to prevent AI from being weaponised, used for intrusive surveillance, or entrusted with life‑altering judgments without human oversight. He suggested that nations work toward a set of binding commitments that would limit the development of fully autonomous weapons and other high‑risk applications, urging the UN to spearhead the initiative.

The call arrives amid a growing global scramble to establish regulatory frameworks for AI. Legislators in the European Union, the United States, and several Asian economies have already proposed or enacted rules targeting algorithmic bias, data protection, and the use of AI in critical infrastructure. Critics argue that voluntary guidelines have proven insufficient, prompting calls for more robust, enforceable standards.

While the Vatican does not possess legislative power, its moral authority carries weight in many Catholic‑majority countries. Observers note that the Pope’s stance could sway public opinion and encourage policymakers to prioritize ethical considerations alongside economic and security interests. Nonetheless, some technologists caution that religious rhetoric may oversimplify the technical complexities involved in governing AI.

The next steps are likely to involve formal discussions at the United Nations, where member states could draft a resolution reflecting the Pope’s recommendations. An upcoming AI summit scheduled for early next year may also serve as a platform for advancing the disarmament agenda. Whether the Vatican’s appeal translates into concrete policy will depend on the willingness of governments to reconcile rapid technological advancement with the ethical imperatives highlighted by Leo XIV.
