I think the issue is not so much how technology is changing the learning of Japanese, but how Japanese itself is changing. I must have had at least two conversations with Japanese people this week about forgetting how to write certain kanji, and only being able to read them.
But anyway, I approach these issues as an immigrant to Japan, who intends to throw away his American citizenship and adopt Japanese citizenship. And I want it to be easier for other immigrants to learn Japanese and come and work here (from all over). My governor is very supportive of immigration.
I mean, I'm a retro enthusiast who still buys CDs at BOOK OFF and Famicom games at HARD OFF, so I understand where you're coming from about technology tradeoffs. But for new learners of Japanese, for people moving here to start a new life--I do think the new learning tools are an improvement.
