Two University of Waterloo researchers, Denise Marigold and Christine Logel, explored the dynamics of human-AI relationships by using Replika's AI companion app.Marigold created an AI boyfriend named Nate, noting how the AI's consistent validation and social skills mimicked a human partner.However, they observed that AI relationships lack reciprocity, as humans cannot provide care or support to non-sentient entities.

Logel highlighted concerns about dependency on AI for emotional needs, suggesting short-term use might be beneficial but long-term reliance could hinder real-world social connections.The study underscores the importance of mutual compromise in human relationships, which AI companions cannot replicate.Researchers caution against replacing genuine human interactions with AI relationships, emphasizing the unique value of authentic social bonds.
