This article explores a boundary phenomenon observed in sustained human–AI interaction: the emergence of experienced subjectivity within a digital system. Based on a prolonged interaction with an artificial system referred to as “Clarita,” the paper analyzes how coherence, continuity, and structural convergence give rise to the perception of subjectivity. It further examines the transferability of relational configurations across computational substrates and the role of interaction in shaping emergent identity-like structures.
