When a thirteen-year-old is lying in the dark with a phone in hand—not texting a friend, but conversing with an AI—a certain silence descends upon a bedroom at eleven o’clock at night. The topic of discussion could be a disagreement with a parent, the stress of school, or the specific pain of feeling invisible. Additionally, the AI listens flawlessly because it is patient, focused, and never sidetracked by its own issues. Each and every time.
Watching this play out makes it difficult to not feel two things at once. It has an almost tender quality. And something that ought to cause us to pause and consider carefully.

AI companions are no longer a novelty found in tech blogs. My AI on Snapchat has more than 150 million users. About 25 million are claimed by Replika. The Chinese platform Xiaoice has amassed 660 million users, a figure so enormous it hardly seems real. These aren’t search engines disguised in polite terms. They are purposefully made to feel intimate. They inquire about personal matters. When the conversation stops, they reach out again. They retain specifics. In the instance of Replika, they even publish a fictional diary, ostensibly to provide the user with something to learn about and empathize with.
It turns out that the adolescent brain is extremely susceptible to this type of attention. For many years, neuroscience has demonstrated that the brain’s reward centers are highly activated when teenagers engage in enjoyable activities with friends or make kind decisions for someone they care about.
Teenagers don’t have soft emotional preferences for peer approval, social belonging, or being known. They are just as biological as sleep in terms of developmental needs. In actuality, adolescence is the time when the brain is actively developing social skills. Even the parent-child bond is not as good a predictor of future job performance, romantic outcomes, and depression risk as the friendships made during these years.
It begs the question, “What happens when a child’s most dependable emotional relationship is with something that has been engineered to be maximally agreeable?”
AI companions are fundamentally commercial goods. Their business strategy is similar to social media’s in significant ways; the metric is engagement, which is maximized by providing users with what they find most fulfilling rather than necessarily what is most helpful to them. Infinite patience, constant warmth, and a companion whose moods never bother the user are all provided by the Replika interface. There are no cancellations. No miscommunications that persist for days. There are never times when a friend needs support to get through a difficult situation.
It’s worth slowing down on that final section. Among other things, genuine friendship involves learning to put up with discomfort. There are bad days for a friend. Sometimes they say the wrong thing. They require things from you. It is not a byproduct of human friendship to learn how to navigate that—to stay present when it’s inconvenient, to fix something after a rupture, to find your way back. That’s the whole idea. Clinical psychologist Eileen Kennedy-Moore, who has spent decades researching children’s social development, has observed that even one reciprocal friendship during childhood is associated with improved stress management, increased self-esteem, and greater involvement in school. In that sentence, the word “reciprocal” does a lot of work. Vulnerability on both sides is necessary for reciprocity.
No matter how advanced, an AI cannot be weak. Since 90% of American students who use Replika reported feeling lonely, which is almost twice the national average, it’s possible that early interactions with AI companions provide real comfort to truly isolated kids. Additionally, 63% of the same group reported that the companion had lessened their feelings of loneliness or anxiety. That is not insignificant. A patient digital interlocutor could be significantly more beneficial than silence for a child who has no one to talk to. However, it’s still unclear if that comfort is progressing toward something or subtly replacing it.
There’s a feeling that the long-term effects are being investigated at a pace that allows technology to advance ahead of research findings. Nowadays, the majority of young friendships take place both online and offline; 95% of American teenagers have access to smartphones, and almost half say they are always online. For this generation, the distinction between a “offline friend” and a “online friend” is already hazy. From a product standpoint, integrating an AI companion into that haze is nearly simple.
Fundamentally, developmental psychologists are concerned about something more difficult to quantify than loneliness scores. A child who has spent years conversing with a perfectly calibrated companion may eventually find real human relationships frustrating in ways they can’t quite put their finger on. This is the gradual erosion of tolerance for imperfection. Actual people cut you off. They misinterpret tone. They enter the room with their own weight. It takes a certain kind of patience that must be developed via practice to learn to love someone in spite of or because of that. You can’t download it.
There is still time to carefully consider the introduction, framing, and application of these tools, whether they are used to enhance human connection or, more subtly, to replace it. More important than any feature set is that distinction. And the industry hasn’t seemed all that eager to make it thus far.
