Central planning?! Computers can do it!!! Among the intuitions animating the contemporary left, we must rank rather high the felt sense that powerful new computing technologies now offer a solution to problems of calculation previously insuperable for the red-eyed central planners of “actually existing” socialist states. This is more or less the central thrust of Leigh Phillips and Michal Rozworski’s recent book, The People’s Republic of Walmart, recapitulating a line of argument expressed in prominent books like Nick Srnicek and Alex Williams’s Inventing the Future and Paul Mason’s Postcapitalism. Walmart and other corporations demonstrate that “economic planning on a massive scale is being realized in practice with the assistance of technological advance, even as the wrangling of its infinities of data . . . are supposed to be possible to overcome” (Phillips and Rozworski 2019: 39) . . .
