Not the case for computing with a material-intrinsic semantics.* > So according to "material-intrinsic semantics" the 4 that a vacuum tube computer produces when it adds 2+2 is not the same 4 that a transistor computer produces when it adds 2+2; and the 4 a white man gets when he adds 2+2 does not mean the same thing as the 4 a black man gets when he adds 2+2, and there is a male 4 when a man makes the addition and a female 4 when a woman does. So how can a serious person consider anything as monumentally silly as a computational theory involving "material-intrinsic semantics"?
