Habermas refined Weber’s rationalization and Marcuse’s technology-as-power into a single thesis.

Evidence

Habermas attempted to define, in a more precise fashion than Max Weber and Herbert Marcuse before him, the phenomenon according to which the rational form of science and technologythe rationality embodied in systems of purposive actionwas expanding to become the historical totality of a life-form. Weber had interpreted this as a process of rationalization' paralleling the process of demystification’ of traditions; Marcuse had attempted to define it as a fusion of technology and power. — Rolf Wiggershaus, The Frankfurt School, 675
