What cybernetics offered economics was not just the power of prediction and control – though that was certainly part of the appeal of the new science – but the possibility of understanding human behaviour in non-human terms. If the economy could be modelled as a machine, the values and meanings that human beings brought to the market could be discounted. Whether they knew it or not, human actors were incidental to the operation of a system that was more rational than they could ever be. The economy was becoming a computer in which human judgement was superfluous.
