Pope Leo XIV on Monday set out a sweeping vision for corporate executives, politicians and individuals who will shape and be shaped by the future of artificial intelligence, warning leaders to safeguard humanity from A.I.’s most disruptive effects.

Leo’s declaration came in the form of a papal encyclical, an open letter to “all people of good will” that ran to roughly 42,300 words in its English version. It outlined his desire to protect human dignity and agency in an age in which technology threatens to replace humans in many professional and social roles. He presented it alongside Christopher Olah, a co-founder of Anthropic, a major A.I. developer, in a symbolic gesture of dialogue between leaders of the spiritual and technological worlds.

While emphasizing that “technology should not be considered, in itself, as a force antagonistic to humanity,” he wrote that “the pursuit of greater profits cannot justify choices that systematically sacrifice jobs.”

Among other things, Leo called for:

government regulation of the private companies that are driving the development of A.I.
protection and retraining for workers whose jobs are threatened
education to help students think critically about the technology
action to protect children from violent, hypersexualized or fake information online that is often generated by A.I.
safeguards to ensure that humans, not artificial intelligence, remain responsible for all decisions regarding the use of weapons.
