The interconnection between digital technology and capital logic has profoundly transformed the production paradigm and lifestyle of modern society, giving rise to new forms of life alienation. Time, space, and subjectivity provide crucial analytical dimensions for understanding the essence of life alienation under digital capitalism, clearly revealing the comprehensive domination of human life by capital. In terms of time, capital leverages digital technologies to blur the boundaries between work and daily life, incorporating individuals’ entire lifetimes into the value-creation chain. Spatially, the pervasive presence of digital platforms reconstructs individual living spaces as potential labor sites, expanding the spatial reach of capital. Regarding subjectivity, capital employs algorithms to render individuals computable, intensifying life alienation under digital capitalism. The marriage between capitalist production relations and digital technology not only reduces technological rationality to a tool for capital accumulation but also reduces human life to calculable, predictable, and controllable productive elements, subordinating individual life logic to the imperatives of capital expansion. Therefore, it is urgently necessary to examine the intrinsic relationship between technological development and life logic through the lens of Marxist political economy, penetrating the apparent neutrality of digital technology to uncover its underlying essence of capital exploitation. At the same time, socialist institutions must regulate the operation of capital, facilitating a transition from capital logic to labor logic, and ultimately overcoming the total alienation of life through genuine communalism.
