«On Guattari's hopes for the transition from the consensual mass-media era to the dissensual post-media era, see "Pour une éthique des médias", Le Monde (6 nov. 1991). Guattari envisages this transition on the basis of four factors:

i) forseeable technological developments;
ii) the necessary redefinition of the relations between producers and consumers;
iii) the institution of new social practices and their interference with the development of media;
iv) the development of information technologies. 

But for many communication theorists, "post media" culture merely provides yet another opportunity to demonstrate that the transition has not been decisive, and to drag out and dust off old models. These theorists should be, as Umberto Eco once put it, "pensioned off'.»
