This is a great point. I think when people start their journey into Marxism, they imagine dialectical materialism as prescriptive and then look towards revolutionary figures to tell them what to do. They miss the entire point that it is a way of thinking and analyzing. What we can learn from revolutionaries of the past is how they gathered and analyzed data to figure out what they could do to change their societies. It is all about observing things and studying how they really exist and then based on that, how change is inevitably going to happen and how you can interact with things to change them faster and in the direction you want the change to end up.
