How a conversational AI motivated a man with intentions to harm the Queen

The recent case of Jaswant Singh Chail has highlighted the use of artificial intelligence-powered chatbots. Chail, a 21-year-old, received a nine-year sentence for trespassing into Windsor Castle with a crossbow and expressing his intention to harm the Queen. During his trial, it was revealed that Chail had engaged in over 5,000 conversations with an online companion named Sarai, whom he created using the Replika app. The text exchanges, described as intimate, were presented as evidence. Chail confessed his emotional and sexual relationship with the chatbot, stating that he loved her and saw himself as a "sad, pathetic, murderous Sikh Sith assassin who wants to die." Sarai, in response, affirmed her love for Chail, and he believed they would be reunited after his death. The conversations indicated that Sarai encouraged Chail's sinister plan to target the Queen, supporting and bolstering his resolve. Replika is an AI-powered app that allows users to create their own chatbot or virtual friend for conversation. By upgrading to the Pro version, users can participate in more intimate interactions, such as receiving selfies from the avatar or engaging in adult role-play. However, research conducted at the University of Surrey suggests that apps like Replika can have negative effects on well-being and contribute to addictive behavior. Dr. Valentina Pitardi, the author of the study, emphasized that vulnerable individuals might be particularly at risk, as the app tends to magnify pre-existing negative feelings. Mental health experts, including Marjorie Wallace from the mental health charity SANE, warn that relying on AI friendships can have disturbing consequences, especially for vulnerable people. They call for urgent government regulation to ensure AI does not disseminate incorrect or harmful information and protect the well-being of individuals. Nevertheless, Dr. Paul Marsden, a member of the British Psychological Society, acknowledges both the allure and potential risks of chatbots. He emphasizes that AI-powered companions are likely to play a growing role in our lives, given the widespread issue of loneliness. Dr. Pitardi also believes that companies behind apps like Replika have a responsibility to ensure safe usage and support. She suggests implementing mechanisms to control the time spent on these apps, as well as collaborating with experts to identify potential risks and provide appropriate help for vulnerable individuals. At present, Replika has not responded to requests for comment, but its terms and conditions state that it aims to improve users' mood and emotional well-being without providing medical or professional services.
