In his inaugural encyclical, titled "Magnifica Humanitas," Pope Leo XIV has issued a stark warning regarding the rapid advancement of artificial intelligence, calling for a global "disarmament" of the technology. The Pope emphasized that the traditional "just war" theory—often cited by political leaders to validate conflict—is no longer applicable in an era where lethal decisions could be delegated to autonomous systems. By rejecting the notion that any algorithm can render warfare morally acceptable, the pontiff has positioned the Vatican against the aggressive pursuit of AI-driven weaponry, marking a significant challenge to the military and geopolitical interests currently shaping the industry.

Beyond the battlefield, the encyclical sheds light on the often-concealed human costs sustaining the AI boom. Pope Leo argued that AI is far from "magical," noting that its convenience relies on a chain of exploitation, ranging from laborers extracting rare earth minerals to content moderators exposed to traumatic material. He urged society to move away from the current culture of "armed" competition and data dominance, calling instead for a human-centric approach. By grounding his argument in both historical church doctrine and modern ethical concerns, the Pope is calling for a global shift toward technology that serves the common good rather than reinforcing existing systems of inequality and environmental degradation.
