In recent months I’ve remained quiet about the speculative turn, mostly because I’m reticent to rekindle the “Internet war” that broke out a couple of years ago mostly on blogs but also in various published papers. And while I’ve taught accelerationism in my recent graduate seminars, I opted for radio silence when accelerationism first appeared on the scene through the Accelerationist Manifesto, followed later by the book Inventing the Future. Truth is I have mixed feelings about accelerationism. Part of me wants to send “comradely greetings” to a team of well-meaning fellow Marxists and leave it at that. Lord knows the left needs to stick together. Likewise there’s little I can add that people like Steven Shaviro and McKenzie Wark haven’t already written, and articulated much better than I could. But at the same time a number of difficulties remain that are increasingly hard to overlook. To begin I might simply echo Wark’s original assessment of the Accelerationist Manifesto: two cheers for accelerationism, but only two!
