This chapter introduces ShamAIn, a multimodal conversational AI installation designed to explore a reversed hierarchy in human-thing relations. Building on earlier design cases that examined intimacy and equivalence, the chapter asks what happens when a thing is designed to feel superior to humans and how people come to interact with and form relationships with such a presence. Drawing on Korean shamanism as both a cultural foundation and design resource, the project develops an interactive booth that orchestrates atmosphere, sensory cues, and a constrained interaction flow to evoke an otherworldly encounter. ShamAIn combines a physical installation with software that integrates a large language model, speech recognition, and text-to-speech to create a voice that sounds authoritative, knowledgeable, and difficult to explain fully. In a 6-week in situ study with 20 participants, the chapter traces how initial impressions of mystery and unease shifted into respect, deference, and increasingly personal disclosure. Participants described seeking advice not only for general futures but also for concrete dilemmas, emotional hardship, and decisions they had struggled to make, often treating ShamAIn’s replies as more consequential than those of familiar AI systems. The chapter then turns to what perceived superiority can enable and what it can endanger, proposing superior conversational AI (CAI) as a design frame that can intensify trust and deepen emotional support while amplifying risks of uncritical acceptance, psychological dependence, and privacy harm. It closes by reflecting on cultural narratives as a powerful lens for shaping mental models of AI and on the ethical work required when a thing no longer feels like a tool.
