It was a hyperbole. But among the people (about 20) who have told me they have used Duolingo to (try to) learn my native language, I have yet to find one who can say more than a few disconnected words. And among the people I have seen who are fluent in my native language or the other languages I speak, I have yet to find anyone who said they used Duolingo to learn that language. Am I extrapolating too much? I think the sample size was pretty good.
