Leo’s first encyclical attacks technological messianism
Pope Leo’s first encyclical, Magnifica Humanitas, is very long (at more than 42,000 words, the length of a short novel). It tackles numerous issues, perhaps too many. The pontiff pleads for fact-checked journalism and multilateral diplomacy. He apologises for the papacy’s belated condemnation of slavery. He declares the concept of “just war”, most recently used by J.D. Vance, America’s vice-president, to justify the attack on Iran, “outdated”. The central purpose of the document, however, is to challenge the unregulated development of artificial intelligence.
