A labor market in rough balance is a strange place to look for an AI-driven jobs collapse. The full-time typist has disappeared, but very few jobs are like that—fully automatable by “AI”:

The Age of Harness Engineering: taming the stochastic parrots before they eat your sead-corn codebase. We’ve scaled the models and blown out the context windows—and discovered that reliability lives somewhere else entirely. Context and prompt tricks got us very impressive demos, but were clearly not enough; now we say “this time! for sure!” and bet on the new frontier of “harness engineering” to turn a stochastic parrot into a halfway dependable co‑worker:

A fond memory of “generous argument” dissolves when you ask who had to swallow what to stay in the room. And do recall Sullivan’s post‑9/11 denunciations of a domestic “fifth column” of the “decadent left” from its “enclaves along the coasts”, and his cheerful embrace of strategic dishonesty over the Bush tax cuts. The through‑line is simple... 1/
