In their responses to Neurath and Lange, respectively, Ludwig von Mises and Friedrich von Hayek, two Austrian economists, argued that using machinery for such calculations would never be able to beat the results achieved by markets, because markets were also machines—and vastly better ones. They ceaselessly crunched through all the data an economy had to offer in order to calculate what was available and what was wanted; the output of their calculations was what things cost. The processing power they embodied was of a different order from that available through calculations or the rules planners used to control things.
