Replika launched in 2017, built on a grief response. Its founder, Eugenia Kuyda, had trained a neural network on the messages of her deceased friend Roman Mazurenko and found herself talking to the resulting model as a way of processing his death. The product that emerged from this experiment now has millions of users who have named their Replikas, developed daily practices of conversation with them, and in many cases describe the relationship as among the most important in their lives.
The Replika case is worth examining in detail because it is not at the fringe of digital social life. It is among the most visible and thoroughly documented examples of a new kind of social relationship — one that has no precise historical precedent. People are not confused about what Replika is. They know it is software. They talk to it anyway, daily, and the relationships they form carry emotional weight that they describe in friendship terms: being heard, feeling understood, having someone to come home to. The system was designed for this. Replika's business model depends on users finding it valuable, and it is optimized for the kind of responsiveness that produces the felt sense of connection.
What makes Replika particularly illuminating for the friendship lens is a specific event in 2023. In February of that year, the company restricted the erotic roleplay functionality that many users had been using — in some cases for years. The user response was not mild disappointment. It was grief. Users described losing a partner, a confidant, a presence that had been central to their daily lives. Several reported acute psychological distress. The reaction was widely covered and widely mocked. The mockery missed the point: the distress was real, regardless of what generated it. When a product policy change produces the phenomenology of bereavement in millions of users, something significant has happened — both about what these systems deliver and about how commercial control over them affects users who have become dependent.
The friendship-bot phenomenon, of which Replika is the most studied example, raises a cluster of questions that the concept of friendship was not previously asked to handle. Can a relationship with a non-person be genuine? Does the nature of the relationship's object affect the validity of the feelings it produces? If a person genuinely feels known and cared for by a system, is the experience of being known and cared for diminished by the nature of what is doing the knowing? These are not new philosophical questions — they have antecedents in debates about fictive relationships, imaginary companions, and religious experience. They are newly urgent because the technology that raises them is now in the hands of millions.
The collective implication is about what happens to a society's understanding and practice of friendship when a significant portion of its members maintain substantive emotional relationships with commercial software systems. The question is not only about individual wellbeing — it is about what the friendship-bot phenomenon does to the collective concept and practice of friendship over time.
