This study provides a philosophical analysis of the attention crisis and “brain rot” phenomenon caused by modern algorithmic recommendation systems, through the lens of Yi Hwang’s Neo-Confucian concepts of Mibal(未發, the state of mind before arousal) and Gyeong(敬, reverential attention). Personalized algorithms fixate user preferences based on past data, weakening the subject’s reflective functions through the “outsourcing of attention.” This paper interprets this cognitive decline as the collapse of Mibal, identifying it as the loss of both mental equilibrium and the subjective foundation for ethical self-cultivation. Furthermore, it argues that the practice of Gyeong, comprising Juilmujeok(主一無適, focused oneness without distraction), Sangseongsong(常惺惺, constant reflective self-awareness), and Jeongjeeomssuk(整齊嚴肅, composed composure), serves as a crucial cultivation model for restoring fragmented attention and reclaiming cognitive resilience in the digital age. In conclusion, this research proposes expanding the discourse on AI ethics beyond mere data bias toward a self-formative dimension of autonomy, aiming to restore the subject’s capacity for moral self-cultivation.
