Pope Leo XIV: Never Delegate Life Decisions to AI
At the Apostolic Palace he urged states meeting in Geneva to ban lethal autonomous weapons and reiterated five principles from Magnifica humanitas.
On Friday, October 30, 2026, Pope Leo XIV received about twenty participants in the conference “The Future of AI: A Dialogue Between the Vatican and the Scientific World” in the Consistory Hall of the Apostolic Palace. The meeting was held that day at the Casina Pio IV and was organized by the Pontifical Academy for Life and the Future of Life Institute.
The Holy Father asked that decisions affecting human life, freedom, and the use of force never be delegated to machines, and insisted that such decisions “must always be subject to effective, informed and accountable human oversight.” He said, “We recognize the direction we must take, but not enough is being done to move forward,” and affirmed, “We have the responsibility to guide, modify and, when necessary, reject” applications of artificial intelligence.
Continuity With Recent Teaching
He recalled Pope Francis’s June 2024 remark to G7 leaders that AI is “a fascinating and tremendous instrument” and that no machine should ever decide to take a human life. He urged states meeting in Geneva in November to take concrete steps toward banning lethal autonomous weapons.
The Pope offered five considerations, continuing his encyclical Magnifica humanitas, published May 15, 2026. First, AI depends on human decisions. Second, machines are tools, not persons; he questioned proposals to grant AI rights or legal personhood because they risk “hid[ing] human responsibility” and leaving those harmed “facing a faceless entity.” Third, technology must not reduce people to data, as in military target lists or border-control databases. Fourth, technology must never become an end in itself or serve “only the interests of a privileged few.” Fifth, the most urgent need is institutions, with “shared standards, independent oversight and clear accountability mechanisms.”
Voices From the Conference
At the conference, Cardinal Michael Czerny, chair of the Interdicasterial Commission on AI, asked, “Who should do what? How can we encourage and even help them to do it?” Archbishop Renzo Pegoraro called for “clearly identifiable human responsibility.” Fr. Paolo Benanti asked for “rules that bind, institutions able to verify, and a person who answers for every decision a machine helps to make.”
Speakers included Max Tegmark of MIT, who warned against transferring decision-making power to machines; Stuart Russell of UC Berkeley, who urged developers to “turn aside from this trajectory before it is too late”; Gary Marcus of NYU; and Valerie Pisano of Mila.
The Church’s concern remains clear: human dignity, freedom, and the right to life cannot be outsourced to algorithms. Oversight, accountability, and the rejection of autonomous lethal force belong to persons created in the image of God—and to the communities and states charged with protecting them.
