The development of biotechnology has made healthcare no longer limited to the general “restoration” of physical and mental functions， but increasingly involves “enhancement.” This has also sparked intense ethical controversies， manifested in deeper thinking about technology and life， human nature， and many other issues. Opponents hold a conservative attitude from the standpoint of humanistic care， believing that the development and use of enhancement technologies pose a serious threat to human society and even human beings. However， looking at their reasons for opposition， many implicit assumptions about the premise of constant health and the stillness of human nature can be found. This not only makes it difficult for their criticism to fully hit the nail on the head， turning them into “inverted” technological determinists， but also reflects a more fundamental misplacement of the relationship between humans and technology， falling into the concealment that Heidegger described as a means of technological unveiling.
