What the Instrument and the Practitioner Owe the World

When a machine acts on people at speeds no human can follow, the obligation to answer for what it does stays with the maker, not the instrument, and that obligation must be built into the design itself rather than discharged in person. The maker owes three things to every person the instrument touches: a reading they can see and contest, a warrant the next hand can inherit and stand behind, and a pace that leaves room for human judgment before the decision has already been made.
