The global financial crisis beginning in 2008 has encouraged the revitalization of a wide spectrum of leftist theorizing, but arguably the most audacious is that of ‘accelerationism’. Left-accelerationism sees the intensification of certain tendencies in late capitalist society as a way to escape its gravitational orbit and ‘repurpose’ the very material infrastructure of capitalism itself, to universally emancipatory ends. The central task here is to engage accelerationism with a thinker of the post-Autonomist tradition, Franco ‘Bifo’ Berardi. Contrary to Williams and Srnicek, co-authors of the #Accelerate manifesto, Bifo asserts that acceleration per se only augments the power and dynamism of capital, and posits instead a ‘post-politics’ of ironic detachment, aesthetic cultivation, and ‘therapy’. Contrasting Bifo and accelerationism clarifies each of their assumptions and core arguments, and points the way to a more nuanced perspective on these issues, in a contemporaneous moment marked in equal measure by inestimable threat and liberatory promise.
