One of the most delicate debates in social robotics concerns emotional dependence. When a companion robot can reduce loneliness, stabilize routines and offer a constant presence, is it doing something valuable — or occupying a space that should belong to human bonds?

What current evidence shows

Recent systematic reviews point to modest, contextual benefits: reduced loneliness among institutionalized older adults and improved engagement in rehabilitation routines. But the authors themselves highlight serious limitations: small samples, short periods and no follow-up.

The problem with irresponsible affective design

There is a difference between a robot designed to be useful in the presence of loneliness and one designed to maximize emotional engagement. The first serves the user; the second may create dependence that serves no one’s interests but the manufacturer’s.

Principles for responsible design

The more serious part of the field is converging on a position: the robot should be explicitly an artifact, not a substitute for a person; it should facilitate — not compete with — human bonds; and it should have mechanisms to refer people to human support when it detects situations beyond its role.
