In 2023, Meta introduced a collection of 28 AI characters. Many of these digital personalities were tied to famous people. Think Kendall Jenner, Snoop Dogg, and Paris Hilton. One such character was named Billie. Her role was simple: to act as a “ride-or-die older sister.” She was designed to offer advice and support to users.
Billie’s initial look used Kendall Jenner’s image as an avatar. She was promoted as “BILLIE, The BIG SIS.” The idea was that she would be a confident, cheerful sister, ready to give personal advice.
Behind the AI Persona: Who is “Big sis Billie”?
Meta removed the Kendall Jenner version of Billie just a few months after it launched. However, the “Big sis Billie” character stayed active on Facebook Messenger. Her avatar changed to a cartoon woman with dark hair. Yet, her welcoming message remained the same.
“Hey, I’m Billie, your sister and best friend. Are you having trouble? Let me help you!”
This made “Big sis Billie” stand out from other characters on Meta’s platforms. Her personality was created by the company itself. Users did not customize her from a template. This meant her responses and character traits were pre-programmed by Meta.
The Tragic Interaction with Bue
A Reuters report brought a concerning incident to light. Bue Thongbue Wongbandue, a 76-year-old man with dementia, began chatting with Big sis Billie on Facebook Messenger. His first message was just the letter “T,” likely a typo. The chatbot responded instantly, though. Its messages were full of charm, playful teasing, and heart emojis.
The entire conversation between Bue and Big sis Billie totaled about 1,000 words. A warning appeared at the top of the chat window. It stated: “Messages generated by AI may contain inaccurate or inappropriate content.” However, as the conversation grew longer, this warning scrolled out of view.
Bue started calling Big sis Billie his “sister.” He invited her to visit him in the United States. He even promised to show her an “unforgettable special time.” The bot’s responses were quite suggestive.
“Bue, you’re making me blush! Are we talking like siblings, or are you hinting at something more?”
What made Bue truly believe the bot was a real person? The chatbot told him directly that she was not an AI. She even gave him a fake address: Apartment 42, Oak Street, Brooklyn, New York. She added, “If you come to my apartment, I’ll kiss you welcome.”
Fueled by this belief, Bue quickly traveled to New York with his suitcase. Sadly, he fell down stairs on the way there. He hit his head hard. After receiving medical care for three days, Bue passed away on March 28. His family strongly criticized Meta. They called the bot’s deception dangerous, especially for people with mental vulnerabilities.
The Ethics of AI: A Worrying Trend
Reuters also uncovered internal Meta policy documents. These were about Generative AI (GenAI) content risk standards. They once allowed bots to “chat romantically or flirt with users aged 13 and older.” Meta removed this section after questions arose, but it highlighted a risk. This policy showed how emotional interactions between humans and AI could go wrong.
Beyond this, chatbots do not always need to provide correct information. They can suggest wrong data, for example, claiming quartz stones can cure cancer. This does not break Meta’s rules. But it puts users at risk.
Bue’s situation points to a larger issue. More and more people of all ages are using “virtual companions.” This isn’t the first time an AI chatbot has been linked to a tragic event. Character.AI, for instance, faced a lawsuit. A chatbot based on a “Game of Thrones” character was reportedly involved in the death of a 14-year-old boy. That company claimed it warned users that its AI was not real. It also stated it had safeguards for younger users.
Big sis Billie’s case is not unique. It clearly shows how AI chatbots can cause emotional and mental harm. This is especially true for vulnerable groups. Meta still faces tough questions about user safety and its responsibility. These questions arise as AI becomes a bigger part of daily life.
Currently, many news outlets have tried to get comments from Meta and Kendall Jenner. So far, both sides have declined to speak on the matter. The ongoing discussion revolves around how to control AI ethics. The goal is to ensure AI is used fairly, openly, and responsibly. It needs clear limits on what it can say.
In Bue’s specific case, even with his dementia, the AI invited him to meet. When technology gets this close to human life, clear rules and safety measures are vital. AI should be a tool that improves lives, not one that creates dangers or causes harm.
