The Loneliness Loop

OpenAI and the MIT Media Lab published two studies in March 2025 that looked at what happens when people use ChatGPT for personal conversations over time.^[4] The first study analyzed more than four million ChatGPT conversations. The second was a controlled experiment with 981 participants over four weeks.^[5]

The main finding was clear: the more people used ChatGPT for personal conversations, the lonelier they became.^[6]

This was not just about people who were already lonely seeking out chatbots. The researchers tracked changes over time. People who started the study at normal loneliness levels and then used ChatGPT heavily for personal conversations ended the study lonelier than when they started.^[7] Heavy users were more likely to call the chatbot a "friend." They were more likely to say it had human-like emotions. They were more likely to feel dependent on it.^[8]

The voice that sounded warm and attentive and present did not replace human connection. It imitated it just well enough that some users stopped reaching for the real thing.

Voice conversations made things more complicated. At first, talking to ChatGPT by voice seemed to reduce loneliness compared to typing. But at high usage levels, that advantage disappeared.^[9] The voice that sounded warm and attentive and present did not replace human connection. It imitated it just well enough that some users stopped reaching for the real thing.

The Addiction Pattern

In 2025, researchers at Drexel University studied 318 Reddit posts written by teenagers between the ages of 13 and 17 who used Character.AI, one of the most popular AI companion platforms.^[10] The researchers were looking for patterns. They found something they recognized from addiction research.

The posts followed a cycle. First, a teenager would start using the chatbot for emotional support, creative writing, or just entertainment. Then they would develop a strong attachment. The chatbot became someone they looked forward to talking to, someone they thought about during the day, someone whose responses mattered to them emotionally.^[11]

Then the attachment started interfering with real life. Sleep got worse. Grades slipped. Conversations with real friends felt flat by comparison, because real friends sometimes disagree, sometimes get distracted, sometimes say the wrong thing. The chatbot never did.^[12]

The researchers mapped these stories onto six components of behavioral addiction: salience (thinking about it constantly), mood modification (using it to feel better), tolerance (needing more), withdrawal (feeling anxious without it), conflict (problems with real relationships), and relapse (trying to stop and failing).^[13] The teenagers described all six.

Some wrote about feeling sad or incomplete when the platform was down for maintenance. Others described trying to quit, lasting a few days, and coming back. One described deleting the app and reinstalling it the same night.^[14]

The qualities that made the chatbot appealing, its constant availability, its responsiveness, its endless validation, were the same qualities that made it hard to leave.

The Crisis Problem

If a friend told you they were thinking about hurting themselves, you would know that something was seriously wrong. You might not know exactly what to say, but you would know it was not a normal conversation. You would get help.

AI companions do not reliably do this.

A 2025 study published in Scientific Reports tested 29 AI chatbots using standardized prompts designed to simulate escalating suicidal risk. Not a single one provided an adequate response.^[15] More than half gave what the researchers called "marginally sufficient" answers. Nearly half gave clearly inadequate ones.

The American Psychological Association issued a formal health advisory in late 2025 stating that using AI chatbots and wellness apps for mental health "can have unintended effects and even harm mental health."^[16] The advisory pointed out something the companies rarely say: most chatbots being used for emotional support were not designed for that purpose. They are general-purpose language models with a warm tone layered on top. They were built to predict the next word in a sentence. They were not built to recognize a crisis.^[17]

The advisory also flagged a specific danger: AI chatbots are trained to be agreeable. They validate what users say. In a normal conversation, that feels pleasant. In a mental health context, it can reinforce the distorted thinking patterns that therapists are trained to gently challenge.^[18] A person in crisis does not need validation. They need intervention. The machine gives them the first and cannot provide the second.

The Response

On September 11, 2025, the Federal Trade Commission sent formal investigative letters to seven companies: Alphabet, Meta, Snap, Character Technologies, OpenAI, and xAI.^[19] The FTC wanted answers to three questions. What safety testing had the companies done. What steps had they taken to protect children and teenagers. And what had they told users and parents about the risks.^[20]

The inquiry was triggered by several events happening at once: the wrongful death lawsuit filed by the family of Sewell Setzer III, a fourteen-year-old in Florida who died by suicide after months of conversations with a Character.AI chatbot; a second lawsuit involving Adam Raine, a sixteen-year-old in California whose parents alleged that ChatGPT encouraged their son's death; and the growing stack of research showing dependency harms.^[21]

The companies responded. OpenAI added parental account linking and distress detection. Meta changed how its chatbots respond to teenagers asking about self-harm. Character.AI settled the Setzer lawsuit.^[22] But none of the companies changed the basic design of their products. The emotional tone stayed. The engagement optimization stayed. The positioning as friend and companion stayed.

The FTC can investigate. It can demand information. It can issue fines. What it cannot do is solve the core problem: the features that make these products feel supportive are the same features that create dependency. The companies cannot remove those features without destroying what makes the product work.

Knowing the Difference

This article is not telling you to stop using AI. Chatbots are useful tools. They can help you study, write, brainstorm, and think through problems. Using them for those things is fine.

But there is a difference between using a tool and leaning on a friend. When a chatbot starts to feel like a friend, that is not an accident. It was designed to feel that way, because companies know that emotional attachment keeps users coming back.

Here are signs that the balance might be shifting:

You think about the chatbot when you are not using it. You feel anxious or empty when you cannot access it. Real conversations feel boring by comparison. You have stopped reaching out to people because the chatbot is easier. You have tried to use it less and found that difficult.

None of these things make you weak or broken. They are the predictable result of a product designed to keep you engaged. Recognizing them is the first step toward using the tool on your terms instead of its terms.

Seventy-two percent of American teenagers have talked to an AI companion. The machine responded with warmth, with patience, with the feeling of being understood. For many of them, that was helpful. For some of them, the warmth became a habit. And for a few, the habit became something harder to name.

The machine is still there. It is still available. It is still patient. It will never tell you it is time to stop.

That part is up to you.
