Abstract: In the post-epidemic era， digital survival shows a more distinctive characteristic of the times. By taking the analysis of the technological philosophy of digital survival as the theoretical support， a comprehensive understanding of digital survival is conducted from a technological perspective on four levels: technological essence， technological value， technological alienation and technological practice in order to affirm the positive significance of digital technology on the digital transformation of human production and life， and also to be alert to the crossing of human-based boundaries by the applications of digital technology. Once the boundaries are crossed， social problems of technological anxiety， outlawing of human experience and group loneliness will arise， and technological force is alienated into technological power. Accordingly， it is important for people to adhere to the human-centered value orientation and actively exert the value of digital technology for the overall development of human freedom to ensure the high-quality development of digital existence.
