I’m from Vietnam. I’ve been in the UK for 10 years now. When I met my English husband 13 years ago at 19 I knew 0 English. We communicated using machine translation. So that’s when I started learning English. Fast forward to present day after immersion, living in an English speaking country, formal study, etc. and I’d say my writing and listening (understanding) are good, but my speaking and reading are still bad. I kind of gave up on trying to become fluent at this point.
No, it simply doesn’t. If one doesn’t want to learn a language, they simply shouldn’t (and this includes wanting to want to learn a language). This is a personal issue, and it should not be an excuse for spreading any kind of misinformation about the topic.
