As well as Japanese animation, technology has a huge influence on Japanese society, and also Japanese novels. I think it's because before, people tended to think that ideology or religion were the things that actually changed people, but it's been proven that that's not the case. I think nowadays, technology has been proven to be the thing that's actually changing people. So in that sense, it's become a theme in Japanese culture.
