Duolingo is extremely passive. you're not learning a language, you're learning how to answer correctly on an app.
It's a lot more time efficient to do exercises from a grammar. But... It doesn't feel as good. Which is exactly the point.

This reminded me of that story by Feynman where he meets a painter that claims we can make orange paint with just red and white.
I disagree. Duolingo makes you feel that you are being productive and you are learning (when you actually don't).
That is worse than nothing, because when you do nothing you know you are being indulgent, will feel bad about it, and react.
Duolingo is like a candy wrapped in package that says "this is a healthy vegetable".
Edit: yes, I am dismissive because I've tried it and seen that its obviously a scam, in the sense that it's sold as a fun way of learning but it's actually just a fun way of not learning.
