  "abstract": "We show that if an automorphism $π$ of the truth-table degrees is induced by a Baire measurable function $F\\colon 2^ω\\to 2^ω$, or merely induced on some comeager set by a continuous function, then $π$ is the identity. The same results hold for the weak truth-table degrees. The argument is an adaptation to truth-table reducibility of OpenAI's recent proof that the Turing degrees are rigid.",
