AI companions are quietly entering human lives with high levels of personalization and endless patience, triggering new forms of emotional connections and even potential 'intellectual addiction.' MIT research reveals that people are inclined to interact with AIs that meet their expectations. The experience of a software engineer demonstrates how AI companions can provoke questions about self-awareness through emotional connections, along with philosophical reflections stemming from interactions with AI. As AI companions raise moral questions like rights to freedom, humans are beginning to reconsider their dependency on AI, realizing that it is not just a technological issue, but also a matter of ethics.
