Based on early Marx’s concept of the species-being, this paper provides a (historical) materialist definition of an ontology of being human and argues that it enables a theorization of a human post humanism. Such theory is based on the fact that cognitive capitalism’s rise of technology translates the human body into literal instruments of labor. However, the link of technology with the laborer enables a transfer of skills and powers that extend the body’s capabilities: creating thus, what this paper terms, the cyber-body. The material reality of this cyber-body is ambivalent: It is a reality of exploitation and abstraction, designed to eventually create infinite capital accumulation, as well as a reality of liberation from the social divisions of class, gender, race, and sexuality by use of its network connecting capabilities. Put together, this ambivalence recovers the real species-being.
