Seeing Like a Finite State Machine

Reading this tweet by Maciej Ceglowski makes me want to set down a conjecture that I've been entertaining for the last couple of years (in part thanks to having read Maciej's and Kieran's previous work as well as talking lots to Marion Fourcade). The conjecture (and it is no more than a plausible conjecture) is simple, but it straightforwardly contradicts the collective wisdom that is emerging in Washington DC, and other places too. This collective wisdom is that China is becoming a kind of all-efficient Technocratic Leviathan thanks to the combination of machine learning and authoritarianism. Authoritarianism has always been plagued with problems of gathering and collating information and of being sufficiently responsive to its citizens' needs to remain stable. Now, the story goes, a combination of massive data gathering and machine learning will solve the basic authoritarian dilemma.
