Have you ever actually tried to learn a language? I'm learning Korean as a native English speaker. I thought it would be a grind, which it kind of is, but learning new words and grammar is actually really fun. I use anki cards and get a dopamine hit whenever I remember the word correctly.
I think my language learning problem is motivation.
Reading this post, that is alot of work, for something that doesn't have clear pay off.
I think it would be cool to be able to speak Spanish and Mandarin(and others) But there isn't that much practicalness for me it especially when everyone speaks English.
