An image of Pope Francis, the leader of the Catholic church, wearing a large, white puffer jacket has gone viral on social media in the past few days. The 86-year-old pontiff looks stylish, with many people commenting on his fashionable clothes. There is just one problem: the image isn't real. The pictures above were generated by the artificial intelligence Midjourney, which produces images based on text prompts, and were posted on Reddit on 24 March by an artist who goes by the name of u/trippy_art_special. The user's account has since been suspended, but one image (the left-hand one) has since spread across Twitter, where it has fooled many.
