The global wave of population aging is advancing at an astonishing pace. According to projections, by 2050 the number of people aged 60 and over will soar to 2.1 billion. Almost every second, more than one person enters this new stage of life. This “silver tsunami” is not only profoundly reshaping social structures but has also given rise to a new field: “silver tech.” Among its most striking representatives are eldercare robots—once the stuff of science fiction, now quietly entering everyday life, reshaping how older people live, and prompting deep reflection on the relationship between technology and familial bonds.

Think back to classic films like Prometheus and Alien: Covenant, with the blue-eyed synthetic “David”—both a loyal scientific assistant and a complex, multi-faceted AI lifeform. These screen creations don’t just satisfy our fascination with technological marvels; they also reflect our long-standing questions about whether machines can possess empathy and free will.

Of course, real-world humanoid robots don’t have such “free will,” and their development is anything but instant. In recent years, advances in AI and robotics have given rise to new forms of embodied intelligence: combining algorithms, machine learning, and humanlike skeletal structures, robots can now mimic human form and movement, perceive their environment, plan tasks, and exercise a certain degree of autonomous decision-making.

In industry, such robots are typically deployed for standardized, highly repetitive tasks—one of the earliest practical applications of “machines replacing humans.” But once they enter the household, their role becomes far more complex and varied. Today’s service robots can help lift older people to their feet, perform basic health monitoring, water plants, hang clothes to dry, or even engage in simple conversation or play music. They’re no longer just efficient “tools” but subtly become “companions” in daily life, introducing an element of emotional comfort into human–machine relationships.

Academia has taken clear note of this shift. Unlike their previously cold, mechanical image, today’s AI systems powered by large language models offer much more humanlike interaction. Their responses can show empathy and warmth, delivering a more humane experience for users. This change is a crucial psychological foundation for people’s willingness to introduce AI “companions” into their lives.

Companies are also tapping into this growing demand. A notable example is the collaboration between Hexagon, a leader in precision measurement technology, and NVIDIA. Together, they've developed a humanoid robot called AEON, designed to combine advanced sensing, environmental awareness, and AI-powered decision-making to better support real-world caregiving scenarios. AEON is equipped with Hexagon’s precision measurement technologies, allowing agile movement and sophisticated environmental awareness. It can fuse and reason over data from multiple sensor modalities to optimize task execution. Such technologies are laying new foundations for applications in eldercare, rehabilitation, and nursing.

In eldercare specifically, AI robots are no longer mere “caregiver substitutes.” They can help some partially disabled patients stand or walk again during rehabilitation. On the emotional side, they try to reduce loneliness through gentle conversation and caring reminders. As aging becomes an ever more pressing issue, eldercare robots could become a vital “shot in the arm” to ease caregiving pressures and fill workforce gaps.

But like all technological advances, there is another side to the coin. Can robots truly “understand” older people as humans do? Are they safe enough, considerate enough, sufficiently “human-like” to be welcomed into the intimate space of home care? Can they really offer high emotional intelligence and attentive care when interacting with people—especially older adults or infants—who have deep needs for emotional connection? The answer is not yet clear.

We need to acknowledge that the development of humanoid robots is unstoppable, but they should never be seen as a “silver bullet” for the challenges of aging. Code and algorithms may simulate warm responses, but they struggle to truly replace human empathy. The ideal future model of eldercare is not a simple case of “machines replacing humans,” but a combination of “machines replacing” for efficiency and “humans remaining” for emotional bonds. Technology should be a “crutch” that lightens our burden and improves efficiency—but it must not, and should not, become a “wall” that cuts off human affection.

Ultimately, the key question isn’t whether to adopt AI eldercare robots, but how we choose to live with them. The answer may remain blurry today, but one thing is certain: only when these machines become more like us—capable of self-correction, flexible responses, and genuinely understanding human needs—will they truly become partners we’re willing to accept and trust in our daily lives.

In the digital age, so-called “electronic filial piety” shouldn’t be a cold replacement, but a fusion of technology with human warmth. It’s along this path that we may find the real balance between technology and human emotion.
