@mbewane , I don't think language learning will be affected. At least not yet.
Most people learn a new language in order to directly interact with people in a different culture.
They don't do it in order to consume their media, which is the value of this tech. So I think you will still have a bunch of people learning Mandarin because they want to do business on the Shanghai river bund, or learning Spanish because they want to serenade an Argentinian beauty. Or any other number of physical reasons.
So The caveat here is that this tech isn't useful for real time translation when interacting with a person. It's too clunky. But I do think it will get there. I'm envisioning something along the lines of integrating elon's neuralink with these AI language models. Imagine a future where you could meet a Vietnamese person or a Igbo person, and immediately have your thoughts translated into their language and broadcast them out loud from your phone speaker, as the other person does the same thing.
Such a thing would be a seamless social interaction that would abolish language learning for all but the most studious of language scholars.
