We should deal with the fact that more people are passionate about topics like Art and Humanities than Math and Computer Science. It's just the reality of academia right now.
Of course it is, because we have these ridiculous stigmas:
Art is passionate, frivolous, and beautiful.
Math is boring, uninspiring, and useful.
What?! There is no such thing as frivolous beauty; no utility is uninspiring and cold. Lockhart, I fear, misses this point. I understand the frustration Lockhart feels at the 'math = boring' stigma, but countering that 'math = art' is just as damning in our obsessed-with-mutual-exclusion society.
Beauty and utility have long been a happy couple. The false rumors of their divorce is, I think, the root of Lockhart's (and my) frustration.
