Three Forms of Acceleration
Rosa's tripartite analytical framework — technical acceleration, acceleration of social change, and acceleration of the pace of life — that distinguishes the mutually reinforcing dimensions along which modernity speeds up.
Rosa's most widely cited conceptual apparatus distinguishes three forms of acceleration that are often conflated in popular discussion. Technical acceleration is the speeding up of goal-directed processes: transportation, communication, production. Acceleration of social change is the increasing rate at which social structures, institutions, and identities turn over — the contraction of the half-life of jobs, relationships, and patterns of belief. Acceleration of the pace of life is the paradoxical subjective experience of having less time despite possessing time-saving technologies. The three forms are analytically distinct but empirically entangled: each accelerates the others, and the entanglement produces the characteristic feel of modern temporality.
