The meaningful world serves as the source of value in people’s daily lives. Marx’s theory of life centers on human beings, with the relationships between individuals and themselves, between individuals, and between individuals and society as its main content. It reveals the essence of the living world and strives to construct a meaningful living world for human beings. The digital intelligence era is reshaping the living world of young people, who are confronting new existential challenges arising from digital shifts, including diversified subject identities, suspended social relationships, and concealed practical fields. The virtual space-time created by digital technology has somewhat eroded the value and significance of young people’s living world, which is manifested in the dissolution of subjects under precise algorithmic logic, moral deficiency in virtual communication spaces, and disorientation of values in the concealed field of practice. Constructing a meaningful world reflects human nature, aiming to promote the free and comprehensive development of individuals. The process of constructing such a world involves a constant pursuit of the spiritual realm encompassing truth, goodness, and beauty. Young people are the drivers of digital technological innovation and the main driving force for building a digital society. Guiding them to actively construct a meaningful world in the digital realm is an essential requirement for promoting their holistic development. It is crucial to awaken young people’s awareness and cognition of this meaningful world, guide them to develop a correct perception of the digital world, strengthen their digital identity, cultivate digital ethics, optimize digital interactions, enrich digital labor practices, and enhance digital cultural experience. This will enable young people to consciously construct a meaningful world amidst the complexities of the digital realm, pursuing the freedom and unity of truth, goodness, and beauty. Through the creation of a meaningful world, young people can deepen their understanding of life and existence, allowing them to dwell poetically in the digital society, create meaningful digital lives, and become digital citizens who are well-adapted to the development of the digital intelligence era.
