But just because most anime have elements of sci-fi doesn't mean all anime are sci-fi anime. Most anime is set in the near future, and a lot of it has technology that currently doesn't exist (for example, the holographic dueling system introduced in Yu-Gi-Oh!). With anime, it's hard to define what is sci-fi anime and what is not. Also, I feel that the genre is unrivaled in creativity, innovation, and philosophical interest. So it makes sense that I find it interesting when fiction speculates about potential futures for humanity borne out of technological innovation.
Well, our generation more than any other saw a huge, rapid growth of technology, and we saw the way new technologies changed society.
