I love this article and couldn't agree with it's central premise more. I can think of no other industry that demands an individual wear as many brain intensive hats as that of the developer today. These jobs which used to be distributed are quickly becoming the baseline for how an individual applicant is judged. I for one believe that if we focus, we can become a true master of skill AND compile that with understanding of the "whole stack" but never being forced to maintain more than our fair share of that stack.
