Other people can better comment on the main theme of this article(which I thought was a great read btw). The point at the start about your first job bending the twig made me think about my own progression. At first I thought "Thats so wrong, I went from Big 5(IT consulting) to Big 4(Accounting) to the startup world". Then I realized that he was right and my experiences at those massive companies is what drove me to where I am today. So to any planning the start of their career, read it, believe it but don't confuse it with saying where you start is where you will stay. Where you start will just help you decide where you want to be.
