Personally, I couldn't disagree more. Specializing to early would narrow your window of opportunities.

A sixteen year old boy doesn't really know what's going to happen during his lifetime. Maybe, one day he would really love to program for a company that specializes in statistics - he would be hopefully lost if he didn’t even know what quadratic equation means.

Another example: in general, you don’t need geography and/or history for your daily job. But you would look pretty stupid if you asked your Swiss customer: “You still have that god save the queen sh*t”.
