In the era of everything-communicated and everything-mediated brought about by 5G technologica linnovation，the cognitive paradigm that regards media as an information transmission tool has lost its explanatory power. Media is naturally an intermediary concept，whose connection attribute has gradually become the most critical media logic with the development of technology. The algorithm that constitutes the “infrastructure” in the intelligent age can be considered as a medium in a higher sense. It connects，matches，and adjusts value relationships through a series of judgment frameworks to shape cognition，build relationships，and integrate society. Understanding the algorithm as a medium not only provides a useful perspective for interpreting the social nature of the algorithm，but also highly summarizes the core logic of media operation in the new communication landscape，which is the connection of value relationships，which has implications for the construction of mainstream media in the future.
