Abstract: Gene editing technology, as the most representative subversive technology in contemporary times, brings huge opportunities for human development while also posing many challenges by modifying life genes. This technology has broken through the traditional definition of life and the once unquestionable realm of life, directly touching on the existing ethical positioning of the intrinsic value of life and triggering a crisis of human dignity. At the three levels of nature, individuals, and society, this crisis of human dignity is manifested as a crisis of life dignity, a crisis of personal dignity, and a crisis of human dignity. To ensure the safety and proper use of this technology, relevant laws and ethical guidelines need to be formulated. Gene editing technology should be based on the principles of "people-oriented, scientific rigor, fairness and openness, early warning and accountability", balance the tension between the development of genetic technology and the value system of life ethics, construct a "soft landing" mechanism for the development of gene editing technology, establish a new ethical cognitive schema and new forms of ethical norms, so as to better safeguard human dignity and promote human development.
