People seek robotic or AI-assisted companions for diverse reasons, rooted in emotional, social, and cognitive dynamics. For some, companionship provides a sense of presence and connection in the absence of close relationships, offering comfort, routine, and a nonjudgmental space for exploration of desires. For others, these technologies serve as a laboratory for personal growth—practice in communication, boundary-setting, or social interaction in a safe environment. The appeal often lies in customization: adjustable personalities, appearances, and conversational styles that align with individual preferences, reducing the friction of social performance. Technological curiosity also plays a role, as enthusiasts explore the capabilities of advanced robotics, AI, and tactile feedback. Yet there are complexities to navigate: the potential for emotional attachment, boundary confusion, and the risk of substituting real-world relationships with artificial interactions. Ethical considerations include consent, autonomy, and the impact on intimate life outside the digital space. As society negotiates these tensions, researchers emphasize balanced use, clear expectations, and supports for healthy relationships. Understanding the psychology behind these purchases can guide designers toward humane, respectful, and privacy-conscious implementations that honor user well-being.
