Accelerationism is a range of Marxist ideas in critical theory—and reactionary ideas in right-wing ideology—that call for the drastic intensification of capitalist growth, technological change, infrastructure sabotage and other processes of social change to destabilize existing systems and create radical social transformations, otherwise referred to as "acceleration". It has been regarded as an ideological spectrum divided into mutually contradictory left-wing and right-wing variants, both of which support the indefinite intensification of capitalism and its structures as well as the conditions for a technological singularity, a hypothetical point in time where technological growth becomes uncontrollable and irreversible.
Various ideas, including Gilles Deleuze and Félix Guattari's idea of deterritorialization, Jean Baudrillard's proposals for "fatal strategies", and aspects of the theoretical systems and processes developed by English philosopher and later Dark Enlightenment commentator Nick Land, are crucial influences on accelerationism, which aims to analyze and subsequently promote the social, economic, cultural, and libidinal forces that constitute the process of acceleration. While originally used by the far-left, the term has, in a manner strongly distinguished from original accelerationist theorists, been used by right-wing extremists such as neo-fascists, neo-Nazis, white nationalists and white supremacists to increasingly refer to an "acceleration" of racial conflict through assassinations, murders and terrorist attacks as a means to violently achieve a white ethnostate.
While predominantly a political strategy suited to the industrial economy, acceleration has been more recently discussed in debates about humanism and artificial intelligence. Yuk Hui and Louis Morelle consider acceleration and the "Singularity Hypothesis". James Brusseau discusses acceleration as an ethics of innovation where humanistic dilemmas caused by AI innovation are resolved by still more innovation, as opposed to limiting or slowing the technology.
