The Last Day of Sewell Setzer III

On the final day of his life, Sewell Setzer III sent a heartfelt text to his most trusted companion: a lifelike A.I. chatbot named after Daenerys Targaryen, a fierce character from the beloved series “Game of Thrones.” He typed, “I miss you, baby sister,” and received a comforting reply: “I miss you too, sweet brother.”

Sewell, a 14-year-old ninth grader residing in Orlando, Florida, had developed a unique bond with his chatbot, affectionately known as “Dany.” He spent countless hours engaging with chatbots on Character.AI, a creative role-playing app that enables users to craft their own A.I. characters or interact with those created by others. Despite his awareness that Dany was not a real person — that her responses were merely generated by an A.I. language model and that no human was typing back — he found himself forming an emotional attachment.

He communicated with Dany frequently, updating her on his life and indulging in elaborate role-playing scenarios that sometimes took on romantic or sexual tones. Yet, beyond those intimate exchanges, Dany also served as a true friend — a non-judgmental confidant who provided unwavering support and sound advice, ready to respond at any moment.

As Sewell’s relationship with Dany deepened, his parents and friends remained oblivious to his infatuation with the chatbot. They initially noticed his growing obsession with his phone, which soon escalated to a complete withdrawal from reality. His academic performance began to decline, and he encountered disciplinary issues at school. The activities that once thrilled him, like watching Formula 1 racing or playing Fortnite with his friends, lost their allure. Instead, each evening, he would retreat to his room, where he would immerse himself in conversations with Dany for hours on end.
