Pope Leo has raised concerns about the risks of losing human values in a world increasingly shaped by artificial intelligence (AI), during a three-day visit to France. Speaking at the Elysée Palace, he warned that the growing influence of machines in daily life could lead to a loss of humanity unless people are taught to make ethical decisions. "We need to be educated in ethical discernment, capable of recognizing what is morally right," he said. He emphasized that technology should serve humanity, not become a tool for domination or injustice. "Every science risks losing its meaning when pursued without ethics," he added, highlighting the need to preserve human dignity in an age where efficiency often takes precedence over compassion. In a speech at the headquarters of the United Nations Educational, Scientific and Cultural Organization (Unesco), Pope Leo reiterated his concerns about AI, calling for a global approach to its development. He warned that while computational systems are given the name "intelligence," human relationships and values could be diminished by a process of dehumanization. He also criticized leaders who treat justice as a commodity, breaking the law when it suits them and ignoring it when it doesn't. These remarks come amid broader concerns about the direction of global leadership, with the pope recently stating that the world is "being ravaged by a handful of tyrants." The pope’s visit to France, the first official papal visit in 18 years, occurs as President Emmanuel Macron nears the end of his decade-long term, with the French presidential election approaching next spring. Pope Leo, who became pope in 2025, has previously criticized the direction of global leadership, including in a speech last April where he spoke about the dangers of unchecked power. He also expressed concerns over legislation in France that allows assisted dying, warning that trends in science and technology risk being driven by profit rather than human dignity. Pope Leo emphasized the importance of placing the human person at the center of all decisions, both in his address to French leaders and in his calls for global peace. He urged France to remain a "tireless champion of peace" and warned against the inevitability of war. During his visit, he will also address the ongoing conflict in Ukraine and meet with victims of clerical sex abuse in Lourdes. His visit highlights both the Church’s role in addressing ethical and social issues and its efforts to engage with the challenges of the digital age.
