coding in outdated languages

I'm a math and chem major minoring in cs. I've been learning Fortran for the past few months because it's got good array handling features. It's still used in computational chemistry and physics even though it's labelled as being outdated. COBOL is still be used in so many business applications on top of that.

Would any of you guys consider teaching yourself one of these "outdated" languages, or is it not even a good idea?
