I think the task is to organize the left so that when the impending collapse comes, we'll have socialism as a safety net from descent into barbarism and chaos. And from the state of things, the left needs quite a bit of time before the collapse to get its shit together.
I'm also wary about totally giving up on states, since at least at this point they offer some resistance to Capital, especially as a recourse for organized workers. This is fraught with peril of course, but I'm not sure we should cede any territory too hastily.
As far as entropy goes, I think it's a result of the intense commodification of time and space (esp. virtual space, which basically is like a free-floating Capital fantasy)... how much more surplus value can you extract from each minute? Capital's reaching a kind of plateau here.
We need something AFTER capital AFTER socialism AFTER it all. After the REAL point of rupture, global rupture. There must be some way out of this tiresome end-game, and if the left have no way of defeating capitalism, then one must think in different directions- indeed the by-product of capitalism is that the very notion of after-capital, of thinking after-capital in an entirely innovative manner becomes blocked. If Capital is as dangerous as it is, why not utilise it as a force that can be turned into just the kind of eschatological EVENT required? Accelerate it, abstract it even further. Of course I'm probably talking abject bollocks here, but I can't see there is anyway to move beyond it other than to ride it, contort it, confront it with its own reals, the flaws in its skin that become ever clearer the further it is stretched taut across the world.
