I’ve been doing daily lessons on it for almost a whole year with the goal of being able to watch anime without subtitles.
I have achieved my goal almost completely. I just need to learn more vocab because DuoLingo has only taught about 150 or so words. Gamifying learning works; if you can stick with it. Which is the whole point in making it like a game: so you stick to it.
Whether or not that will continue to be the case when everything is handled by AI has yet to be seen. I am doubtful, considering how fucking God awful LLMs are at providing ACTUAL info and not just creating a madlib with what it has been trained on.
Just DuoLingo, watching Japanese stuff without subtitles (including cultural guides for further understanding) to force myself to listen, and then looking up words I don’t know when I come across them.
My goal was never to learn how to speak or write anything; just understand it well enough to watch Japanese media in the original language. I still often have to rewind and play back stuff to get it all. Especially if they are saying a long sentence really fast.
It also probably helps that Language itself is one of the things that tickles my autistic brain.
