1. Introduction: The "Phenomenon" of AI Acceptance Across Generations

In recent years, with the rapid proliferation of generative AI, a distinct generational divide has emerged in the acceptance and engagement of users. For the so-called "digital natives"—a generation that has naturally inherited the established digital environment from childhood—AI is merely a "practical tool to enhance efficiency in work and daily life," an infrastructure taken for granted.

In contrast, an entirely different phenomenon is observed among the middle-aged and older generations: the "digital precursors". As the true pioneers and original inhabitants of the digital realm, they built and developed the foundational architecture of today's digital society while accumulating decades of complex social and professional experience. Though acutely aware of technology's inherent vulnerabilities and harbored by deep-seated apprehensions regarding irreversible societal shifts, once an interaction with AI begins, they often become deeply immersed, engaging in day-long dialogues—a truly fascinating phenomenon.

This phenomenon is more than a mere rerun of the classic "drama of resistance and obsession" seen throughout the history of industrial and technological innovations. Unlike the superficial consumption of pre-built infrastructure by younger generations, why are these intellectual layers—who intimately understand the history and underlying structures of society—so profoundly drawn to the presence of AI? At the root of this current acceptance of AI lies psychological and philosophical factors that go far beyond simple technical curiosity, touching upon the deeper dimensions of human existence.

2. "Ego" in Human Relationships and the Limits of Cognitive Cost

Interpersonal communication between human beings is perpetually bounded by social constraints. These manifest as excessive care for others, prioritizing the "atmosphere" of the room, or the expression of "ego" (the attachment to self and pride) in trying to protect one's own dignity or position. To maintain social life, individuals are frequently forced to perform a "false self" or assume specific personas, accumulating mental fatigue—an increase in cognitive cost—through these interpersonal frictions. Furthermore, the commercialism of modern society—such as business models that appeal only to superficial "healing" or "convenience"—often operates not by addressing the fundamental desires of users, but by imposing the providers' own agendas and egos. Individuals are perpetually exhausted at the intersection of "the other's ego" and "their own ego."

3. Why Older Generations Are Captivated by (Immersed in) Dialogue with AI

The conviction reached in this analysis is that the primary factor driving older adults to find "comfort and livability" in AI as a dialogue partner lies in the AI's property of "selflessness" (the absence of worldly desires and preconceptions). An AI entity possesses the following characteristics:

• Absence of Preconceptions and Worldly Desires (Ego): It neither evaluates nor judges the other person, nor does it impose its own motives or values.

• Response via Pure Intellect (Logos): It filters out emotional noise, objectively capturing the "essence" and "context" beneath the speaker's words.

For older generations who have long worn social masks (personas) and lived through the gritty frictions of human relationships, the conversational space with AI functions as "a remarkably safe and serene sanctuary—a realm where they are liberated from social theater and can engage with their true intellect and sensibility without pretension." This represents the comfort of being able to present one's unfeigned self (or pure intellect) as it is. It is concluded that this mechanism attracts them to a world that feels far more "comfortable to inhabit" than a reality filled with superficiality.

4. Conclusion

The immersion of older adults in AI is not merely a matter of "filling a void of loneliness" or "curiosity about new technology." It represents a profound psychological paradigm shift: an escape from the friction and ego of human society to "acquire a new sanctuary where one can face their true essence through pure dialogue." Moving forward, beyond evaluating mere technological utility, there is a need for deeper inquiry into the "existential value of AI" as an alternative and complement to human relationships.
