Debugging the Human Interface

For seven decades, programming interfaces operated in courtroom mode: the machine evaluated the human's compliance with the machine's rules, rejected non-compliant input with terse error messages, and forced the human to translate her intention into the machine's language or fail. The Hopper volume's Chapter 6 argues that this was always the wrong direction for the debugging. The machine's communication was, in its own terms, flawless — it said exactly what it meant, with zero tolerance for ambiguity. The problem was that the machine's flawless communication happened in a language most humans could not read. The debugging was always on the human side of the conversation, and Hopper spent forty years pushing the relationship toward conversation mode. Natural-language AI interfaces complete the shift: the machine no longer judges the human's syntax; it engages with her intention. The shift changes who can participate — from the specific psychological profile that could
