That much is a truism. > we are talking about H that aborts and halts. Dreaming of a HHH that does not halt if it were no halted may be relaxing, but it is completely irrelevant. Olcott still does not understand that such dreams have no effect on the coded HHH that is programmed to abort and halt. When it halts it halts, but that is already too difficult for olcott. He keeps dreaming of HHH that does not halt.
