Can't disagree more. Learning a spoken language is much more than picking-up a communication tool - it opens a world of culture and thought that is bigger than the language itself. Yes, the same can be said of mathematics, and both are as valuable.
I'm European, speak 3 languages and use math every day, professionally. I've studied, lived and worked in the US for many years and am often shocked at some of my American friends' lack of perspective on international affairs.... keep-up with the math education but don't do it at the cost of languages... you can't afford to.
