Haven't read the article yet, but I re-learned the language my family lost about 3 generations ago. Studied over there in university, returned to my ancestral village... felt like it filled in a missing piece. It feels a bit like a superpower now to be able to read news in another language (or two) in order to get a different perspective on the world.
If I go three generations back (great-grandparents), I'd have to learn at least three languages other than english. It can be rewarding to learn this stuff, but it scales about as well as hyphenated last names.
