As someone with a philosophy degree and many years of formal training in classical music, I give this piece a hearty thumbs up. While the author clearly values the liberal arts (um, it's McSweeney's), there's something to be said for actually getting things done in the world. A lot, actually. What the author is parodying is less the degree itself but more the miles wide and inches deep approach to education and life…
In terms of "getting things done in the world," how is making iPhone fart apps any more of a contribution than, say, publishing a screed in a tabloid? I'm trying not to set up a straw man here, so I'm deliberately choosing lowest common denominator activities.
I don't think it's fair for us technical folk to rest on our laurels simply because we have mastery over some very specific kind of knowledge that has a great deal of useful applications. We have to get out there and get real things done, too.
