Does AI Feel Pain? Dietterich Uses Painkillers as a Litmus Test for Machine Suffering

tdietterich · x · 2026-10-08

In a debate over a paper on whether models subjectively experience pain, Plinz asks what criterion could ever be convincing. Turing Award winner Thomas Dietterich half-jokingly proposes one: painkillers interrupt or dampen pain, so check whether an artificial system reacts the same way. He adds a sharper point: the Conscious Turing Machine (Blum & Blum) models pain but clearly doesn't experience it—so any criterion a CTM can satisfy is insufficient to prove experiential pain in a computing system.
