I don’t think so. Some people can pick up languages relatively easily, and some people can’t. I don’t really know how AI could solve this, unless you mean that the AI can ferret out your gaps and tune the program to your learning needs. Isn’t this what Duolingo tries to do? Genuinely asking. I pay for the “super” Duolingo for no ads and unlimited learning because I’m kind of addicted to it, but I plan trips to Germany every year because you really do need immersion to get to even basic fluency.
