Marx is staging a comeback. The philosopher and social revolutionary, not the comedians. His analysis keep coming up in conferences and articles as a useful framework to read and understand some of the transformations occurring in today's networked world. At Reboot in Copenhagen in June, professor Adam Arvidsson spoke about the concept of "general intellect" introduced by Marx in 1857 - what we would today call "social intelligence". Chris Anderson's recent bestseller "The Long Tail" makes a strong case for how culture has been shaped by the physical infrastructure of distribution and access, reflecting classical Marxist thinking that the "infrastructure" determines the "superstructure". Now Kenneth Cukier, who's a tech correspondent for the Economist, sees a "postmodern form of Marxism" in Yochai Benkler's book "The Wealth of Networks". As he writes in a discerning review published this week in the New Statesman: "Like Marx’s social revolution, Mr Benkler’s technical one promises to bring out man’s better nature, forgoing self-interest for the benefit the community (through sharing open-source software, contributing to Wikipedia, penning blogs, etc.)".
