I do not accept the founder of Duolingo as an authority on education, because Duolingo sucks at teaching people things. I accept him as an authority on getting people to waste time and money on (enjoyable) games that make them think they are learning. I 100% believe AI could be used for that.
1215 day streak on Duolingo for French. Yeah it’s not great if you’re serious about learning a language. It’s more akin to doing the daily crossword. They gave me a week free-trial to Duolingo MAX (the AI version of the app) and I did not particularly like it.
Duolingo MAX is also like double the price of Super (the basic paid subscription)
