Just like a lot of AI-related statements, I strongly disagree with this one. I wouldn’t have the level I have in English without Mr Fleury’s awesome English class in year 11/12.

Also, TIL that Duolingo is using user’s data to model learning behaviors?. This makes a ton of sense for a free app to use our data in return.
