Well there are two options as to "acceleration"- either the "chaos" effectively removes whatever the barrier IS which is created by this latest form of capitalism to innovative thought, or instead of chaos Capital is pushed into a new form, bringing with it unimaginable change.
Also Land effectively fails to effectively differentiate between the merely churning changing same of fashion and the shocking ontological shifts of the new (though weirdly he alludes to it). This is cos both he AND the positions he criticises fail to effectively differentiate the fact that Capital shifts through eras, each bringing their own inimitable costs and benefits, and changing regimes of political organisation, changing flows of productive energy. Whats interesting to me is how THIS Capital of now has given rise to effects quite distinct from those of 40 years ago, and how we can intervene to change those effects.
But lots and lots of ideas in that article that I agree with, especially about Capitalism and time, and the need to adopt a position INSIDE capitalism, that the flaw in post-Marxist thinking is that in all its avowed immanence it never ever deigns to get INSIDE the infernal machine itself, that it is itself the one system (and not the proletariat) capable of delivering the unimaginable change. But the miserablists are accurate when they point to the fact that presently the de/re-territorialization of time has led to an utterly deadlocked moribund position of un-death, a cancerous ahistorical replicator effect, dyschronic grey goo eating the planet, all dead-eyed death-drive...
