The presuppositions conceal the existence of a question which _does_ need consideration in the present, though the conditions under which it will become immediately relevant are unpredictable. There will of course be revolutions (i.e., dissolutions under chaotic conditions of present regimes).
What is not at all certain (I would say what is unlikely) is that such revolutions (a) will be _socialist_ revolutions and (b) whether, if socialist and if (temporarily) successful, such revolutions will _remain_ socialist rather than succumb to counter-revolution (internally or externally generated). We can then say that not only are revolutions (i.e. chaotic collapse of regimes) certain, but so is the counter-revolution. The deceptive demand for a scenario for revolution, then, is obscurantist by its nature (whether by intention or not is irrelevant and unanswerable in most cases), for it forecloses the vital questions of how, within non-revolutionary conditions preparations can be made for the (concretely unforseeable) conditions of chaos which will periodically emerge and reemerge so long as capitalism survives.
