The transformative power of artificial intelligence (AI) is redefining the respective roles of humans and machines in the creative process and challenging the theoretical paradigm of authorship in traditional copyright law. The current practice of equating AI subjectivity with authorship based on abstract logical deduction is particularly worthy of reflection. In fact, confirming the author identity is actually an effective social organizational means for the copyright mechanism to realize the tilted distribution of creative resources, and it is a distribution technology that provides actual qualifications to different personality subjects. Through the general legal definition of abstract subject qualifications, it can be concluded that the authorship of AI is a logical error. By systematically sorting out the historical genealogy of authorship ideology, this article believes that authorship in copyright law is not a simple projection of the “romantic” view of authorship, but the result of the participation of post-structuralism and relational authorship theory. It emphasizes the original meaning of the author to the work, and highlights its own symbolic construction value and its function of encouraging cultural exchanges and social interaction. The “romanticization” of AI authorship ignores the human element of the author concept and its ethical characteristics that serve the just value of copyright distribution; poststructuralist theory is not entirely motivated by the disenchantment of the romantic author myth, but focuses on the symbolization of the author identity to deconstruct and eliminate the traditional elements of authorship and break the established consensus of copyright law. Therefore, it cannot be used to realize the theoretical justification of AI authorship, because AI cannot meet the social subject position of relational authors on cultural dialogue and meaning exchange, and cannot participate in the network of human social relations, excluding the possibility of becoming an author. This article expandsprevious literaturein the following two aspects. First, it strictly distinguishes the subjectivity of AI from the confirmation of identity qualifications, and uses authorship in copyright law as a unique research perspective and analysis toolto judge the reasonableness of AI's authorship status in copyright law. Second, it places the legal concept of authorship in copyright law within the context of dynamic social construction, reveals the different historical genealogies of authorship ideologies in copyright law, and uses this as a theoretical premise to evaluate the appropriateness of AI authorship. This article scientifically grasps the essential connotation of authorship in the evolution of the concept of authorship in copyright law, systematically refutes various theoretical tendencies on the issue of authorship in AI, and lays an important foundationof methodology and normative theory for the scientific understanding and explanation of authorship in the era of AI. This will help copyright law return to the people-centered institutional logic and serve the great mission of promoting human creative progress and the prosperity of human cultural undertakings.
