H(D,D) is being asked the question: Must your correct simulation of D be aborted to prevent your own non-termination? It answers that question correctly. All undecidable decision problems make this same sort of mistake. Incorrect yes/no questions have no correct yes/no answer. -- Copyright 2024 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see." Arthur Schopenhauer
