I don't know about the whole argument but the linked article includes interesting bits such as:
The scene is Kentish Town, London, February 1858, sometime around 4am. Marx is a wanted man in Germany and is hard at work scribbling thought-experiments and notes-to-self. When they finally get to see what Marx is writing on this night, the left intellectuals of the 1960s will admit that it “challenges every serious interpretation of Marx yet conceived”. It is called “The Fragment on Machines”.
In the “Fragment” Marx imagines an economy in which the main role of machines is to produce, and the main role of people is to supervise them. He was clear that, in such an economy, the main productive force would be information. The productive power of such machines as the automated cotton-spinning machine, the telegraph and the steam locomotive did not depend on the amount of labour it took to produce them but on the state of social knowledge. Organisation and knowledge, in other words, made a bigger contribution to productive power than the work of making and running the machines.
Given what Marxism was to become – a theory of exploitation based on the theft of labour time – this is a revolutionary statement. It suggests that, once knowledge becomes a productive force in its own right, outweighing the actual labour spent creating a machine, the big question becomes not one of “wages versus profits” but who controls what Marx called the “power of knowledge”.
In an economy where machines do most of the work, the nature of the knowledge locked inside the machines must, he writes, be “social”. In a final late-night thought experiment Marx imagined the end point of this trajectory: the creation of an “ideal machine”, which lasts forever and costs nothing. A machine that could be built for nothing would, he said, add no value at all to the production process and rapidly, over several accounting periods, reduce the price, profit and labour costs of everything else it touched.
Once you understand that information is physical, and that software is a machine, and that storage, bandwidth and processing power are collapsing in price at exponential rates, the value of Marx’s thinking becomes clear. We are surrounded by machines that cost nothing and could, if we wanted them to, last forever.
In these musings, not published until the mid-20th century, Marx imagined information coming to be stored and shared in something called a “general intellect” – which was the mind of everybody on Earth connected by social knowledge, in which every upgrade benefits everybody. In short, he had imagined something close to the information economy in which we live. And, he wrote, its existence would “blow capitalism sky high”.
I also liked this:
Is it utopian to believe we’re on the verge of an evolution beyond capitalism? We live in a world in which gay men and women can marry, and in which contraception has, within the space of 50 years, made the average working-class woman freer than the craziest libertine of the Bloomsbury era. Why do we, then, find it so hard to imagine economic freedom?
It is the elites – cut off in their dark-limo world – whose project looks as forlorn as that of the millennial sects of the 19th century. The democracy of riot squads, corrupt politicians, magnate-controlled newspapers and the surveillance state looks as phoney and fragile as East Germany did 30 years ago.
Sadly he over rates womens' freedom but the point is tolerable in context.
