Did the Pope use AI to write about the dangers of AI?

An analysis posted on LessWrong, run through the AI detector Pangram, suggests that parts of Pope Leo XIV's new encyclical may have been written with AI — even though the document warns about the risks of AI. Telltale signs include unusually frequent phrasings typical of models like Claude. A second pass found roughly 62 percent AI content in the first chapter. The Vatican has not yet commented.
