Pope Leo welcomes increased dialogue on AI, but continues to share existential concerns | CBC News

On Friday, Pope Leo XIV began a four-day visit to France by warning that unchecked technology could threaten humanity. He raised questions about human identity amid artificial intelligence, nuclear weapons and other dangers.

Leo has made AI a central concern since becoming pope. His first encyclical called for strong rules and urged developers to put the public good ahead of profit.

He said some technology leaders appear willing to ensure AI serves people rather than replacing or harming them. He also called on developers and political leaders to proceed carefully as demands grow for safeguards.

The visit is the first official papal state trip to France in 18 years, and large crowds are expected. Leo spoke to President Emmanuel Macron and officials, urging France to uphold the right to life as a basis for other rights.

His remarks came as France has protected abortion rights in its constitution and lawmakers approved a bill allowing assisted death for adults with incurable illnesses. Leo also called on France to support peace and international cooperation, especially in Europe; Macron described the visit as a source of hope.
