I am very successful in my secret identity life, so no, this is not some kind of grass-is-greener observation; rather, it's an attempt to give practical advice to my younger selves out there. I majored in math and physics, and did well, and am in the world now, and can concretely see the ways that a CS education would have helped me, ways that people less smart than I am think better!

As soon as I graduated with a CS degree I realized I should have been in philosophy the whole time.

I'm comparing CS only to other technical majors.

CS is not something everyone can fall in love with and think about in the shower and over lunch and drifting off to sleep.

I'm not proposing CS as an academic discipline, but as a discipline for training the mind for work in the world.

Do I know the intricate details of every reader's intellectual life? Do I claim that everyone who's currently majoring in math or econ drop it and switch to CS?

To quote Robin:
