Artificial life technology has enabled humanity to transition from passive observation of life to active creation of life, a shift that has overturned traditional definitions of life and the foundations of ethics. The ontological foundations of life undergo technological innovation, reshaping the dialectical relationship between contingency and necessity. This triggers issues such as the commodification of life and the shift in ethical responsibility toward posthumanism, plunging the principle of naturalness into an ontological crisis. Technological philosophy offers a lens to examine this ethical dilemma, revealing a dialectical relationship between technology and ethics marked by tensions including speed differentials, paradigm conflicts, and power paradoxes. In response, this paper proposes reconstructing the ethical approach to future artificial life technologies. This includes refining the distribution of ethical responsibilities by clarifying the duties of scientists, policymakers, and the public; achieving a paradigm shift in ethical frameworks by establishing interdisciplinary research platforms and multi-stakeholder ethical review mechanisms; and constructing a global ethical consensus framework to address the multifaceted challenges posed by artificial life technologies.
