150 years is blink of a second in the order of history. Think about how long feudalism has lasted and how long it took bourgeoisie to eliminate the ruling class. Also, it's debatable if Russian Revolution was a communist revolution per se. There is sufficient literature that goes both ways, i.e. arguing it was more of a bourgeoisie revolution against the monarchy than a proletarian revolution. Of course, Marx himself predicted (which is not a prediction of his theory) that a communist revolution will happen in his lifetime. It might be him overfitting to his own era which saw successive revolutions. I personally don't find this a big deal since it doesn't have any important implication to materialism. It just makes Marx's prediction wrong. For an updated/modern view on Marxism: https://en.wikipedia.org/wiki/World-systems_theory https://en.wikipedia.org/wiki/World-systems_theory
