On Monday, Pope Leo XIV released his first encyclical, titled Magnifica Humanitas, or magnificent humanity. The 83-page letter is about “safeguarding the human person in the time of artificial intelligence,” and warns that AI power shouldn’t be concentrated in the hands of a few private companies, that jobs should be protected, and that there should be greater oversight and regulation. Christopher Olah, co-founder of Anthropic, was present at the briefing, and got a shoutout from the pope.
