Pope Leo XIV has issued his first encyclical, "Magnifica Humanitas," advocating for international regulation of artificial intelligence. Released on May 25, the document emphasizes the need for binding laws to prevent AI systems from making lethal or irreversible decisions. The Pope warns against the unchecked power of major AI developers, highlighting risks such as disinformation, autonomous warfare, and job displacement. The encyclical stresses the importance of legal frameworks and independent oversight over voluntary industry ethics. It argues that AI-driven disinformation could threaten democratic systems and that automation should not come at the cost of employment. Anthropic co-founder Christopher Olah's presence at the Vatican underscores the alignment between AI safety research and the Church's call for transparency and accountability in AI systems.
