The idea of inevitable and linear progress is a terrible myth that needs to die.
Aren't you a Marxist? You might need to ditch the whole "capital's internal contradictions will inevitably lead to its internal collapse and revolutionary overthrow by the proletariat who will then seize control of the economic apparatus created by the bourgeois for their own benefit" aspect if so and you believe that inevitable linear progress is a myth.
Well yes, but the revolution won't happen if we sit back and watch; progress must be pushed for by the working class itself.
