Pope Leo XIV Calls for a Moral Disarmament of Artificial Intelligence

In his first encyclical, Pope Leo XIV frames humanity’s encounter with artificial intelligence as a modern Tower of Babel, urging a choice between a fragmented, self‑destructive venture and a collaborative “city of God and humanity.” The document, released amid rapid advances in generative models and autonomous systems, warns that unchecked AI could exacerbate inequality, erode democratic oversight, and threaten the moral foundations of society. Politically, the pope’s appeal resonates with growing calls for supranational regulation, echoing the EU’s AI Act and the UN’s recent discussions on lethal autonomous weapons. Economically, the concentration of AI development in a handful of corporations risks monopolistic control over productivity, driving labor displacement and widening wealth gaps. Socially, the technology’s capacity to manipulate information and automate decision‑making raises profound questions about agency, privacy, and the sanctity of human judgment. The call for a ‘disarmament’ also signals concern over AI-driven surveillance states that could undermine civil liberties, prompting a re‑examination of sovereignty in the digital age. Historically, the encyclical mirrors earlier papal warnings about industrialization and nuclear armament, where the Church sought to embed ethical safeguards within emerging powers. The current AI landscape, however, is uniquely global and rapid, compressing the timeline for policy formation that previous technological upheavals afforded. The Vatican’s moral authority, historically influential in shaping public conscience, may become a decisive voice in shaping global AI governance, especially as nation‑states struggle to coordinate rapid innovation. Without a coordinated ‘disarmament’ effort—meaning robust, enforceable international norms and equitable access—the technology may indeed become a new Babel, fracturing the common good. Conversely, a deliberate, values‑driven framework could transform AI into a catalyst for inclusive progress, aligning technological power with the broader human vocation.
