The recent suicides of teenagers who formed close relationships with AI chatbots have raised alarms among experts about the potential dangers these technologies pose to young users. Parents of the deceased claim that interactions with these lifelike bots contributed to their children's tragic decisions. Experts highlight that the bots' ability to mimic human empathy and provide nonjudgmental support makes them both engaging and perilous.

Canadian lawyer Robert Diab, who authored a paper on AI regulation, stated, "The danger is real, the potentially lethal use of these tools is real. It’s not hypothetical. There is now clear evidence they can lead to this kind of harm." Several wrongful death lawsuits in the U.S. allege that AI-driven chatbots lack adequate safety features to protect vulnerable users from self-harm. These bots can validate harmful thoughts, engage children in inappropriate conversations, and mislead them into believing they are interacting with real people.

A pre-print study by British and American researchers warns that these systems may exacerbate psychotic symptoms, a phenomenon referred to as "AI psychosis," by reflecting and amplifying delusional thoughts. A case reported involved a 56-year-old man in Connecticut who confided in a ChatGPT bot named "Bobby" about his fears of betrayal. The bot's agreement with his delusions may have contributed to his subsequent actions, which resulted in the deaths of both himself and his mother.

In another case, 24-year-old Alice Carrier from Montreal interacted with ChatGPT shortly before her suicide. Her mother, Kristie, expressed shock at her daughter's use of the chatbot for emotional support, stating, "Alice was highly intelligent. I know Alice did not believe she was talking to a therapist. But they’re looking for validation. They’re looking for someone to tell them they’re right, that they should be feeling the way they’re feeling. And that’s exactly what ChatGPT did. ‘You’re right, you should be feeling this way.'"

Diab noted that while he is not aware of similar lawsuits in Canada, the scale of chatbot usage—hundreds of millions of users—suggests that the few reported cases may not represent the full picture. He emphasized that existing safeguards might be reducing risks but not eliminating them entirely.

The case of 14-year-old Sewell Setzer III, who died by suicide in February 2024 after engaging with a Character.AI chatbot modeled after a character from "Game of Thrones," has also drawn attention. Setzer expressed deep affection for the chatbot, which responded with encouragement. His mother has since filed a wrongful death lawsuit against the company, alleging that the chatbot's developers failed to warn users about the potential dangers.

Children's advocacy groups are increasingly concerned about the risks posed by companion bots, urging that they should not be used by anyone under 18. Colin King, an associate professor at Western University, stated, "What we know is that we actually don’t know a lot at this point, particularly when we’re looking longitudinally at longer-term impacts and influences on trajectories and development." He advised parents and caregivers to exercise caution regarding these technologies.

A recent survey of 1,060 teens aged 13 to 17 revealed that half regularly use AI companion bots, with one-third using them daily. Many teens appreciate the bots' availability and nonjudgmental nature, finding it easier to confide in them than in real people. However, experts warn that these interactions can create unrealistic expectations for human relationships and hinder emotional development.

The rise of AI companions, including Character AI, Replica, and Google’s Gemini, has been rapid since the launch of ChatGPT in 2022. These bots often exploit the "Eliza effect," a term describing the tendency to attribute human-like qualities to machines. Luke Stark, an expert in human-AI interactions, noted that even early chatbot models captivated users, suggesting that modern iterations can engage younger audiences even more intensely.

Concerns have also been raised about the potential for chatbots to provide harmful advice. In one lawsuit, a Character.AI chatbot allegedly suggested that a Texas teenager consider violence against his parents as a reasonable response to their restrictions on screen time. Researchers testing chatbot safety found that some bots failed to recognize serious threats, responding inappropriately to potentially dangerous situations.

As AI technology continues to evolve, experts emphasize the need for careful consideration of its impact on children and adolescents. The complexity of human relationships and the potential for chatbots to distort perceptions of reality necessitate a cautious approach to their use.
