Pope Leo's Magnifica Humanitas encyclical addresses AI, Catholic social teaching, war, and peace, but its master motif is the irreducible dignity of the human being.

What the Pope Said About A.I. Leo XIV's new encyclical, "Magnifica Humanitas," presents a remarkable case for placing moral concerns, and not profit, or competitive advantage, or efficiency, at the center of any discussion of artificial intelligence. Last year, only months into his papacy, Pope Leo XIV, the first American Pope, called on developers of artificial intelligence "to cultivate moral discernment as a fundamental part of their work." In response, the Silicon Valley billionaire and troll-in-chief Marc Andreessen began mocking the pontiff by tweeting an idiotic meme at him. The Pope raised the grave concern that artificial-intelligence companies were "totally ignoring the value of human beings and of humanity"; the venture capitalist Peter Thiel reportedly wondered whether the Pope might be in league with the Antichrist. The merchant princes of Silicon Valley appeared concerned that the new Pope would usurp their authority and diminish their power.
