For the same reason so few people major in any subject. CS isn't special. People major in subjects because they're interested in them, they think the career path might be good, there is social prestige, and many other reasons. It's entirely not surprising that CS has few people selecting it as a major. The decline or slower growth relative to other fields requiring similar kinds of intelligence may be an interesting question--or it may not be, but the posted article doesn't, in my view, present any compelling case for either answer.
