I don’t think that will ever be a replacement for living somewhere the language is spoken. I believe true fluency requires that (unless you’re some kind of savant) and I don’t think AI can replace the experience of walking into a shop, reading all the signs and labels in the language, making small talk with others in there, talking to the cashier. It’s that kind of immersion in a language that combines not only practice reading, writing, and speaking the language, but also all the other sensory experiences that reinforce what you’ve learned and forms associations that deepens your understanding.
