he pleasing nature of algorithms leads their reward mechanisms to focus on attracting users, which may trigger various issues concerning privacy, cognition, and emotion. In human-computer interaction, there is tension between algorithm stickiness and relationship boundaries. Taking relationship intimacy as the core objective can lead to a series of problems, such as the degradation of social skills and the decline of social cohesion. At the same time, the interpretability trap is intertwined with the Pygmalion effect, which exacerbates users’ emotional dependence and misunderstandings of the essence of technology, forming an emotional manipulation “black hole”. To build a healthy human-computer relationship, algorithm design should abandon the idea of simply enhancing relationship intimacy as the core goal and seek a fundamental balance among performance, interpretability, and user independence. The regulatory level also needs to be continuously strengthened to ensure that technological development aligns with human interests, thereby achieving harmonious coexistence and coordinated development between humans and machines.
