Just a year ago, Katrina Berg was at the pinnacle of her career. She was a rising star in the AI chatbot start-up everyone was talking about, married with an adoring husband, and had more money than she knew how to spend. Then her world combusted. Her husband, Jason, was killed in a fiery car crash. Her most prized possession is the beta prototype for a new, ultra-sophisticated chatbot loaded onto her phone. The contents of Jason's email, social media backups, pictures, and every bit of data she could find were loaded into the bot, and Katrina has "talked" to him every day for the past six months. She has been amazed at how well it works. Sometimes, she imagines he isn't really dead and is right there beside her. On a particularly bad day, she taps out: Tell me something I don't know. The cursor blinks for several moments and seems frozen before the reply flashes quickly onto the screen: I think I was murdered.
