Was Pope Leo once a celebrated jazz trombonist in the 1970s and 1980s? That's the false claim from a musician who, as a joke, posted an AI image showing someone who looks similar to the new pontiff playing a trombone at a concert. The post gained enough traction that the Pope's own brother told AFP news agency that rumours of the head of the Catholic Church once having a secret musical life were false. So, what does this say about AI's ability to mislead after years of advancements? Should there be more restrictions on AI-generated images, and how dangerous can they be? Elvis Yu takes a closer look.
