The author quotes long division as an outmoded skill. So let's all use our IPhones instead, insuring that the genius of arithmetical computation and algorithmic thinking, which took generations of scholars to discover, will be abandoned for a black box from your favorite vendor. That way, only scribes (ie. mathematicians) will know what's going on underneath the hood, just like the old days. Hey, I've never used regression analysis either (same argument) so why bother with math at all.
