Subjective value is interesting especially in the digital economy as we move along, specifically digital products, services, and ai. Surplus value I think still holds, and many of his big observations on the results of capital accumulation directionally have played out perfectly since industrialization with little resets along the way by way of anti-trust, and boom-bust cycles. Feels like we're entering a very different paradigm tho. Decentralization of money, renewable energy, digitization, and Ai were never accounted for in any economic models. A lot of economists try to shoehorn one or two into the system we have now. I feel all of these things are too base layer (fundamental) and composable for the status quo.

Marx was important. He explained capitalism in a way nobody had yet, and his ideas were an important tool for subsequent economists and thinkers to develop a better understanding, and build better models. Most take the mention of Marx as a grand ideological position. I don't. His ideas simply get added to the mosaic of economic intelligence through the centuries, and it gives us all a richer understanding. Things as old as that, preserved through writing (this can include music) don't survive at large in the global consciousness if they have no value.
