The ideology of Accelerationism assumes that, in doing so, you bring about an inevitable contradiction/clash that, by working through the contradiction, will eventually result in a better world. This is not always the case, and in many cases the catastrophe/disaster resulted in a large shift Right.

I think Accelerationism preys on Leftism by pushing an over-systematizing thinking towards our current environment to the point where human agency is moot. I think both Althusser and fell into this kind of Accelerationist thinking.

Now, we can do some lower-case acceleration, like organizing a union in your workplace. That would accelerate a clash between management and your coworkers. It also means we aren't relying on hardship and pain, but good argument and comradery, to convince people of our views.
