Pope Leo XIV on Thursday expressed concern over the increasing use of artificial intelligence in warfare, arguing that the technology sets up a moral dilemma for humanity. 

The pontiff’s warning came during a speech at Rome’s La Sapienza University, in which he called for expanded oversight over AI being developed and used in the military “so that it does not absolve humans of responsibility for their choices and does not exacerbate the tragedy of conflicts.” Leo, the first American pontiff, is expected to issue a similar admonition in his first encyclical set to be released on Friday, according to Axios.
