A promise is a promise: A love letter from the <scp>ACH</scp> to the world of 2050^†

ABSTRACT Experiments in money often recapitulate long‐standing human concerns over finality and fixity, despite money's reference points in political authority, trust, and the memorialization of relationships of credit and debt. From the point of view of the primary set of infrastructures facilitating the movement of money in 2050, those concerns are misplaced. Recounting the history of those infrastructures, this love letter from a future intelligence is addressed to those humans who would reimagine money so that they will recognize the human and technical infrastructures on which it has always depended.
