Artificial life technology has enabled humanity to transition from passive observation to active creation of life，a shift that challenges traditional definitions of life and ethical foundations. As the ontological foundations of life undergo technological innovation，the dialectical relationship between contingency and necessity is reshaped， resulting in issues such as the commodification of life and the shift in ethical responsibility toward post - humanism. These changes have led to a crisis in the principle of naturalness. Philosophy of technology offers a critical framework to examine this ethical dilemma，revealing a dialectical relationship between technology and ethics marked by tensions like speed differentials，paradigm conflicts，and power paradoxes. In response，this paper proposes a reconstruction of the ethical approach for future artificial life technologies. First，it is important to refine the distribution of ethical responsibilities by clarifying the duties of scientists，policy makers，and the general public. Second，it is recommended to achieve a paradigm shift in ethical frameworks by developing interdisciplinary research platforms and pluralistic ethical review mechanisms. Lastly，efforts should be directed toward constructing a global ethical consensus framework to address the multifaceted challenges posed by artificial life technologies.
