To reduce the value of software to its capacity for monetization, as Terranova suggests, leaves unspoken the enthusiasm and creativity in evidence in open source movements. Perhaps the latter are better thought of as a collective practice of supererogation seizing on the wealth of opportunities already produced by capitalism as a historical product, in the form of hardware and software platforms, and which breaks the loop whereby this wealth is reabsorbed into the cycles of exchange value. This invocation of the open-source movement is a powerful reminder that there are indeed other motivating value systems that may provide the 'libidinizing impulse' that Fisher calls for in the search for alternative constructions; it also recalls Firestone's call for a cultural revolution in which the distinction between aesthetic imagination and technical construction is effaced.
