nah, I don't think that the Japanese culture will disappear.

Societal structure has remained basically unchanged for centuries on end. Politicians get old and move, Beaurucrates still rule and will rule.

Language may change and probably has since most can't quote Basho, or any other famous works. But language is a living entity, and I don't think it's possible to keep the Japanese in the land of Genji.

The amount of Japanese is different if you compare it to the voice overs. Even the sentences are different.

I just finished watching Stand by Me ... if they wrote out all the script, I'd still be reading while the move had already finished. So it has to do probably with the amount that youu can visually read and yet still be able to see most of what's going on in the scenes.

"I wonder if you will ever have friends like when you were 12?" ... or something like that.

Definitely a very good reason to study
