Roy Christopher (2002) 'Peter Lunenfeld interview', Rhizome Digest, 5 Oct.

In Snap to Grid (2002) Peter Lunenfeld introduces the term 'dialectical
immaterialism,' to contribute to critical discussions about technology untethered to the constraints of production' - this is a misunderstanding of the term 'immaterialism' in the sense that autonomists use it at least absolutely connected to production. 

McKenzie Wark <nettime> on material and 'immaterial' labour, June 1, 2002. 

The concept of 'immaterial labour' is much misunderstood. Labour is both material and immaterial as Mckenzie Wark points out (2002b). He thinks there has been too much emphasis on labour in the 'over-developed' world (and in the work of Hardt and Negri), in the emphasis of information over matter. In fact, 'the immaterial comes to exist precisely "because" it becomes a form of property;' more precisely in the form of intellectual property (2002b).
