Sharing is inevitable

Recently I got acquinted with Paul Mason and his ideas. In his book 'PostCapitalism - A Guide To Our Future' he tells about an essay that Karl Marx never published:

In the 1858 Fragment, however, we are confronted with a different model of transition: a knowledge-based route out of capitalism, in which the main contradiction is between technology and the market mechanism. In this model, scribbled on paper in 1858 but unknown to the left for more than 100 years, capitalism collapses because it cannot exist alongside shared knowledge. The class struggle becomes the struggle to be human and educated during one’s free time.

I think Marx and Mason know what they are talking about. And it's great to see one talk about this subject.
