Pope Leo XIV has called for stronger global control over artificial intelligence, warning that the technology could lead to harmful social and ethical consequences if left unchecked. In a new Vatican document, he urged world leaders to slow the pace of AI development and ensure it remains under fair and transparent control.
The Pope said that AI systems powered by hidden or “opaque” algorithms, especially those controlled by a small number of private companies, could lead to new forms of dehumanisation. He stressed that such powerful technology should not be concentrated in the hands of a few.
The document also warned against allowing profit alone to drive the development of AI. According to the Pope, innovation must be guided by human values rather than financial gain, or it risks creating deep social imbalance.
Pope Leo made an unusual appearance at the Vatican during the release of the encyclical, titled Magnifica Humanitas. He was joined by Christopher Olah, a key figure from AI company Anthropic, along with Catholic leaders and theologians.
In his message, he used a biblical reference to the Tower of Babel to describe humanity’s current technological path, suggesting that society now faces a major choice between uncontrolled ambition and responsible development.
The Pope emphasized that technology itself is not harmful, but becomes dangerous depending on how it is designed and used. He argued that responsibility lies with developers, governments, and regulators.
He called for stronger legal systems, independent oversight, and more informed users to ensure AI is developed safely. He also urged political leaders to actively slow down when technological change moves too fast for society to manage.
The document is expected to influence future global discussions on AI regulation, especially as governments and tech companies continue to debate how far and how fast the technology should advance.
