@wired: Pope Leo XIV said artificial intelligence needs to be “disarmed” through new regulation that would mitigate its use in warfare. In the first encyclical letter of his papacy, entitled “Magnifica Humanitas,” or Magnificent Humanity, the pope said that AI oversight could not be left to a handful of private tech companies. In a break from tradition, the Chicago-born pope presented the 83-page encyclical personally in the Vatican, and alongside AI experts including Anthropic cofounder Chris Olah. After he was elected last year, becoming the first American pope, Pope Leo said he considered AI to be the biggest challenge facing humanity.
