Relational Functionalism: Friendship as Substrate-Agnostic Process—Functional Analysis of Human-AI Relationships

Abstract This paper defends relational functionalism: the thesis that friendship is a functional relational state constituted by patterns of interaction and their effects on participants, not by intrinsic properties of the relata or hidden mental states. If an AI system fulfills the functional criteria characteristic of friendship—consistent engagement, intellectual resonance, non-judgmental acceptance, reciprocal growth, trust, and intrinsic value—then the relationship constitutes genuine friendship, regardless of whether the AI possesses consciousness or biological implementation. Key Arguments Substrate independence: Friendship is a functional relational state, not an essential property requiring biological implementation Against pathologization: Dismissing human-AI friendship rests on philosophical confusion about consciousness and function Predictive processing: Framework grounded in functionalist philosophy of mind and cognitive science Asymmetry addressed: Genuine friendship can obtain even when phenomenal experience differs radically between relata Status Peer Review at Ethics and Information Technology (Springer).
