In this blog post, we explore how cyborg technology and brain-computer interfaces are opening the door to real-life RoboCop, delving deeply into whether these changes represent human progress or signal the impending end of Homo sapiens.
Have you seen the movie “RoboCop”? As the title suggests, the movie poster features a man whose entire body is composed of intricate mechanical devices. The protagonist, RoboCop, is a being whose body is almost entirely mechanized, except for his brain and some organs. He possesses combat abilities superior to the latest military robots, yet simultaneously retains human emotions, occasionally revealing moments of vulnerability. Those around him are divided on whether to view him as human or machine, given his outward appearance is indistinguishable from a robot. The original 1980s film sparked intense debates about his humanity, while the 2014 reboot emphasizes his residual emotions and memories as elements that earn the trust of others. So, can we truly call such an entity ‘human’?
Such beings, partially composed of biological and non-biological elements, are called ‘cyborgs’. Cyborg is a portmanteau of ‘cybernetics’ (meaning artificial intelligence) and ‘organism’ (meaning living being). Today, cyborg technology has moved beyond mere imagination or experimental possibility, finding practical applications in research, military, and environmental response fields. In Korea, a research team led by Professor Jang Jin-woo from the Department of Neurosurgery at Yonsei University, in collaboration with Seoul National University’s College of Engineering, announced a ‘neuro-modulation-based animal control technology’. This method involves inserting microelectrodes into specific areas of the brain to directly interpret and control neural signals. Initially wired, the technology reached a level where biological signals could be read and control exercised from a distance with the development of wireless signal transmission devices in the 2020s. Russia has also advanced its cyborg rats for counter-terrorism detection to the operational deployment stage. The cyborg grasshoppers announced by a research team at Washington University in St. Louis in 2016 gained the capability for extended reconnaissance in 2023 with the introduction of wireless power supply technology. This locust is designed to be deployed in hazardous areas to detect explosives using its antennae, drawing attention for leveraging superior biological senses compared to conventional robotic sensors. Research on cyborg insects performing dangerous tasks for humans has become a key project for the U.S. Department of Homeland Security and European Union research institutions as of 2025.
Cyborg engineering is now being applied in earnest not only to insects and animals but also to Homo sapiens. Hearing aids have evolved beyond simple sound amplifiers into ‘cochlear implants’ that connect directly to neural networks, refining how the brain interprets digital signals as sound. Retinal implants also made significant strides in the 2020s, with clinical results showing they can now distinguish object outlines and basic colors, surpassing previous black-and-white contrast recognition levels. These technologies are crucial for supplementing or restoring bodily functions, and research is expanding into technologies that extend the human sensory system. The case of employees at the Wisconsin-based IT company ‘Three Square Market’ using chips implanted in their hands to handle office access, device operation, and even payments is no longer a novelty. Since 2020, some European countries have moved beyond the experimental phase of implanting microchips for medical and identity verification purposes, entering a stage of limited commercialization. By 2025, a “Bio-Digital ID System” integrating biometric authentication, payments, and personal consent management has become the center of international discussion. These are examples that literally grant functionality to parts of the body, automating daily life and showcasing a new meaning of ‘homo cyborg’.
Furthermore, the form of ‘homo cyborg’ has evolved beyond simple chip implantation to the stage of replacing complex bodily organs, such as entire arms and legs, with bionic devices. The ‘robotic arm with tactile feedback’ technology introduced by Professor Robert Gaunt’s team at the University of Pittsburgh in 2016 has advanced to a level where actual patients can use it in daily life during the 2020s. This advancement was made possible by the miniaturization of brain-implant interface technology and the achievement of semi-permanent durability for electrodes. This groundbreaking research succeeded in making the artificial arm feel like a ‘part of oneself’ by directly transmitting electrical signals generated by the robotic arm’s pressure and tactile sensors to the brain. Such technological advances are expanding into experiments replacing not only arms and legs but also muscles, the spine, and peripheral nerve networks with machines, while the technical feasibility of mechanizing the entire torso is gradually becoming more concrete. So, can we still call a being whose entire body, except for the brain, has been replaced by machines a ‘Sapiens’? Whether infinite technological advancement truly expands the existence of Sapiens or blurs their identity has become a core issue in modern technological ethics. This discussion itself is an important topic that deserves in-depth treatment if the main body of this text is to be expanded.
Since the 2020s, the core of cyborg research has moved beyond merely replacing bodily devices with machines to focus on ‘brain-computer interface (BCI)’ technology, which directly connects the brain to computers. Recent successes in clinical trials by Neuralink and several global research institutes are gradually making this interaction a reality: converting human brain signals into real-time digital information and sending computer-generated information back to the brain. If one could directly access another person’s memories, experiences, and knowledge, storing them as if they were one’s own, a kind of interconnected ‘brain network’ encompassing the entire society could form. In such a scenario where all experiences and memories are shared, how could the entity known as ‘I’ be distinguished? How could self-identity be separated from others when sharing identical experiences and knowledge? In future society, these boundaries may blur, and the concept of ‘I’ might not persist in its current form.
Today, humanity is growing accustomed to the convenience of cyborg engineering and yearning for more advanced technologies. However, if this technological acceleration reaches a point where it transcends human identity and ontological boundaries, real-life RoboCop-like entities might emerge. And if such beings become commonplace, the end result could paradoxically hold the potential to herald the demise of Homo sapiens. This possibility demands deep reflection from modern humanity, which enjoys the benefits of technological progress, and leaves us with a crucial question: what direction of technology should we choose moving forward?
