It will take a lot of time for your Japanese language skills to get up to par with robot translation, that is true. It was also arguably true with google translate many years ago too.
But isn't this true for most things? It will take a complete beginner years to draw as technically proficiently as an image generation model, or to code as well as Claude. Even before AI, most Japanese media has been available in English translations for years now, and there aren't that many other interests where you could find Japanese speaking peers but not English speaking ones.
If your goal in life is to generate the most economic value per unit of time input, maybe then learning to draw, code, or speak Japanese no longer makes sense. And if that's your priority, you won't choose to do these things. But that's not why people take up these pursuits. So I don't think AI will have a huge impact on how many people start them.
