I don't think that is the Capitalism that is dying, the system we live in is that is dying - but it is not the Capitalism per se.
Things will always have value, but this value changes along time, but people will always need to trade.
What we are facing now, is the beggining of the decay of the State. I explain: the value of things are changing including the human work. Now we have automation, highly efficient industries, 3D printing, digital media, robot, but we still need work, even ifpart of it can be supplyed by technology. At the end it will reflect in lower wages, but on the other side the production cost are also lowering.
What is really in jeopardy is the Government. There will be a point, not far away, we won't have resources to sustain a corrupt and inefficient State. What will come next will depend on how the powerfull politicians will accept their loss of power. Anarchy, war, communism, feudalism, technocracy, remember Capitalism is only an economic system.
