Sure, today hacking is "cool" .. because money, fame and power are cool and many hackers have achieved that. But until very very recently (last couple years), the only reasons a kid would start hacking were curiosity and having little else to do because they couldn't (or didn't want to) fit in.
With that in mind, this article disturbs me in a way I can't easily explain. Particularly when she describes feeling like an imposter "in the face of the desirable hacker stereotype" and even claims the nerdy clothes that hackers wear are in and of themselves exclusionary simply because one might choose to be more fashionable.
This is no different from her stereotypical "hacker" complaining about having to wear different attire to fit in at a school dance (or should he/she later choose to go into banking, law or any profession other than programming at a startup).
I went to a top high school, where academic excellence (grades, SATs, AP tests, what college you got into, etc) was definitely cool and admired. Even then, if you saw a kid hacking in the hallway (or painting or otherwise working on things completely of their own choosing) you knew that he/she was likely at the bottom of the social totem pole.
These very people are who pg was speaking to in many of his early essays like http://paulgraham.com/nerds.html
The fact of the matter is that a disproportionate number of the best hackers come from that population. Those who were the "cool kids" in high school may want in now, but they'll have to earn their place at the table. If that means working ungodly hours, having to change the way they speak or dress to "fit in" .. when in Rome ..
