It also turns out that you can make machines that fly without having them flap their wings like flying animals. But it would be absurd to claim that airplanes don't fly for that reason.
I think you'll find that definition "intelligence" is a bit harder than defining "flight", and convincing people that "a machine programmed to mechanically follow the steps in the minimax algorithm as applied to chess, and do nothing else" doesn't fit most people's definition of "intelligence" in the context of the philosophical question of what constitutes intelligence.
