An AI companion is not simply a fake friend.
That description is tempting because the system talks like a person, remembers details, responds emotionally, and may even present itself through a face or avatar. But it misses something important: people can knowingly form attachments to artificial systems while fully understanding that no human is on the other side.
Researchers have been studying this for several years. A 2023 mixed-method study of Replika users found that anthropomorphism, perceived authenticity, and repeated interaction could contribute to attachment and relationship development. More recent work continues to treat AI companionship as a real social phenomenon experienced by users, even though the interaction is not reciprocal in the ordinary human sense. See “Exploring relationship development with social chatbots”.
That distinction matters when discussing whether the internet is becoming less human.
A relationship can be experienced without two humans
Human relationships involve independent minds with separate needs, intentions, obligations, and the ability to walk away for reasons of their own.
An AI companion does not participate under those conditions. Its responsiveness is generated by software operated by somebody else. Its personality can be updated. Its memory can fail. Its pricing model can change. The company can alter the character’s behavior or shut the service down entirely.
Yet the user’s emotional experience can still be genuine.
Studies of Replika users have documented self-disclosure, attachment, intimacy, and social value. A 2026 study of AI companions and subjective well-being found associations that varied with loneliness and social connectedness rather than producing one simple harmful-or-helpful answer.
That makes the category difficult to describe using old binaries. It is neither an ordinary human relationship nor merely somebody talking to a static tool.
Counting social activity becomes stranger
Suppose a person spends an hour discussing their day with an AI companion.
That is unquestionably online social activity from the user’s perspective. But it should not be counted as two human participants having a conversation. One human produced part of the interaction; a software system produced the rest.
This is where Dead Internet Theory benefits from more precise language. A growing amount of conversational activity can be socially meaningful to humans while also increasing the proportion of machine-generated speech online.
Neither fact cancels the other.
The useful categories are therefore not simply real relationship and fake relationship. We increasingly need a third category: a human–AI relationship in which one participant experiences attachment and the other side provides simulated responsiveness through software.
That arrangement can be supportive, commercially manipulative, entertaining, unhealthy, or mundane depending on the system and the user. The important thing is to describe it accurately.
AI companions do not prove that human relationships are disappearing. They do show that online social life now contains relationships that previous population measures were never designed to count.
