AI and War: A New Pope’s Call for Careful Rules

The latest message from the Vatican says that smart machines should not be left to a handful of people and that they could make fighting easier. The Pope wrote that wars are now driven by new tech, and he wants rules to keep the human spirit safe. He says old ideas about “just wars” are out of date and that weapons only belong to self‑defence in the strictest sense. The document also apologises for past church mistakes, like supporting slavery and being slow to speak against it. The Pope compares AI to the Tower of Babel, warning that a single power could make people lose their identity.He stresses that different voices must shape the future of machines and that technology should protect jobs, respect nature, and be governed by clear laws. He says AI is not neutral; every tool carries the values of its makers and can decide who matters. The release included a tech founder, showing that the Vatican wants to talk directly with those building AI, not just observe from afar. In the past year he has spoken out against “over‑friendly” chatbots and urged priests not to use AI for sermons. A new Vatican commission will study how these tools affect people. The Pope hopes the document is more than words – it should spark real change, just as earlier papal letters inspired environmental action.
