@landley You just hammered my knee-jerk reflex: THE TURING TEST AS WIDELY UNDERSTOOD DOES NOT EXIST. (Ahem.)
Turing's original paper "Computing Machinery and Intelligence" set up the thought experiment really badly: it's really a test of whether a chatbot can emulate performative feminity—gender-coded language. It says more about Turing (gay Englishman from a quasi-monastic single-sex background) than about AI.
(You're not wrong about the "first cut" thing, but …)
