Vatican City, Nov 7, 2025 / 14:41 pm (CNA).
The story of a mother whose son committed suicide after interacting with a chatbot moved participants at an AI conference in Rome on Friday, underscoring what Pope Leo XIV described earlier in the day as Catholics’ moral and spiritual responsibility for the development of artificial intelligence (AI).
An MIT researcher nearly broke down in tears as he recounted the experience of the woman, Megan Garcia, who herself took part in the conference and spoke there to experts in robotics and AI.
“I apologize for being so emotional because it is so emotional,” said Jose J. Pacheco, co-director of the MIT Advanced Manufacturing and Design Program, speaking at the Builders AI Forum at the Pontifical Gregorian University on Nov. 7. He said Garcia’s story illustrated “how urgent this conversation needs to be, how urgent this conversation is, and how much responsibility we have.”
In a message to the conference, which was read aloud to participants on Friday morning, Leo said the development of AI “cannot be confined to research labs or investment portfolios. It must be a profoundly ecclesial endeavor.”
He urged all AI creators to “cultivate moral discernment” and put technology at the service of every human person.
AI, the pope wrote, “carries an ethical and spiritual weight” because “every design choice expresses a vision of humanity.” He called on builders of AI “to develop systems that reflect justice, solidarity, and a genuine reverence for life.”
“Whether designing algorithms for Catholic education, tools for compassionate health care, or creative platforms that tell the Christian story with truth and beauty, each participant contributes to a shared mission: to place technology at the service of evangelization and the integral development of every person,” Leo XIV said.
The two-day Builders AI Forum brought together Catholic ethicists, entrepreneurs, educators, technology experts, and health care professionals from more than 160 organizations across the United States, Europe, Latin America, Asia, and the Vatican. Hosted by the Pontifical Gregorian University and sponsored by Longbeard, the company behind the Catholic chatbot Magisterium AI, the event aimed to form an interdisciplinary community to guide AI innovation through the lens of Catholic social teaching.
In small working groups, participants discussed AI’s impact on education, health care, and business. Educators debated how much children should interact with chatbots, while health care experts questioned what the “essential role of a human” in medicine could be in an increasingly automated system.
On the sidelines of the conference, young Catholic entrepreneurs pitched new AI tools and applications to potential investors, and professors exchanged ideas with practitioners over cappuccinos. Despite differences in opinion, participants broadly agreed that Catholics — with their intellectual and ethical tradition and focus on human dignity — must help shape AI’s future.
Josh Thomason, CEO of TrekAI, an Atlanta-based Catholic tutoring startup, said he attended to “come together with like-minded believers to think together about where we are today and how we iterate towards what that future is.” He added that “it is critical that people of faith are ultimately working in this space to shape it.”
John Johnson, CEO of Patmos Hosting and the Albertus Magnus Institute in California, urged participants to offer a “human alternative” to the commodification of people by technology.
“Every tech company that invented this technology … has the same exact product and that’s you, and that’s me,” Johnson said. “The Church … is called to stand up and very aggressively, even triumphantly, pronounce … the transcendent alternative to the commodification of the human person.”
Pope Leo XIV, the first American pope and a former mathematics major, has made ethical technology one of the key priorities of his papacy. He said he chose his papal name in part to honor Pope Leo XIII, who addressed the challenges of the industrial revolution in his encyclical Rerum Novarum.
“In our own day,” Leo said shortly after his election in May, “the Church offers to everyone the treasury of her social teaching in response to another industrial revolution and to developments in the field of artificial intelligence that pose new challenges for the defense of human dignity, justice, and labor.”
Leo XIV praised the AI Builders Forum for fostering “dialogue between faith and reason renewed in the digital epoch,” saying that “intelligence — whether artificial or human — finds its fullest meaning in love, freedom, and relationship with God.”
