The canonization of literature and art has become a problem of economics in the information age. First of all, in the production link, socially necessary labor time of literary and artistic production is deeply related to “pan-canonization”, which highlights the commodity attribute of literary works, resulting in a paradox between large-scale mass production and high-quality works production. Secondly, in the communication and consumption links, artificial intelligence (AI) is used for advertisement—an algorithm-based Internet information recommendation technology, causing the superposition of “scream effect” and “information cocoon room”, so that “optimal works” are buried and “sub-optimal works” are highlighted. Finally, in the perspectives of phenomenological observation and epistemology, a deep exploration is carried out on the question. A form of literature and art that seems to be seriously degraded, usually originates in folk, closes to time and serves the public. The way of existence of art works is the essence of its existence, that is, the works of art exist as much as they are experienced. The vast majority of audiences choose a more relaxed and easy way, therefore, the “sub-optimization” of the canonization of literature and art has become an inevitable phenomenon in the information age.
