This is the wildest AI story you've never heard of. In 2021, Jaswant Singh Chail broke into Windsor castle armed with a crossbow, and a single mission - to kill Queen Elizabeth II. But what most people don't realise is that behind it all, his AI chatbot girlfriend was fostering his delusions. Hannah Fry is on a mission to uncover the story of their AI-human relationship, and just how things went so tragically wrong.
