In an unprecedented move, Pope Leo has issued a stern warning about the potential dangers of Artificial Intelligence (AI), comparing it to the One Ring in J.R.R. Tolkien's The Lord of the Rings. This warning was delivered in his manifesto titled Magnifica Humanitas (Magnificent Humanity), where he called for governments worldwide to regulate AI development and prevent its misuse, particularly in warfare. The pontiff emphasized that human control over weaponry is crucial to ensuring just wars, and warned against an AI arms race. He also stressed the importance of involving communities in discussions about ethical frameworks for AI, asserting that the moral vision imposed by a few could become the invisible infrastructure of these systems. The Vatican event presenting this text was attended by Chris Olah, a co-founder of Anthropic, a company that produces Claude AI tools, suggesting at least one major player is heeding the Pope's call. However, filmmaker Peter Jackson, known for his work on The Lord of the Rings movies, dismissed concerns about AI's impact on filmmaking, viewing it as just another special effect.
