I didn't read it as coming to the same conclusion as the original, because the meat story presupposes that we who are meat already know that the aliens are wrong. (Maybe that's a humanist reading of the original, but okay). I didn't read this one as trying to make a case that we are fools for assuming that matrix multiplication can't be intelligent... I think its point was that it can't be intelligent, and that people trying to judge it the way mechanized aliens would judge meat creatures just makes them sound ridiculous.
