that day night not be that far off, with advances in holographic technology. Recently developed technology to bend light. And the soon to become common electronic paper that will allow moving pictures on paper, like the Harry Potter world news papers.
Will we have the spartan clean worlds of most scifi? Will we have a realistic future that looks like Blade Runner? Or will we go through a retro stage and end up with a Potter-esque future?
Personally I think it will be a Blade Runner like world. As much as we say we like clean lines and open spaces, the truth is, people are messy and like their clutter. I think it's some odd nesting instinct that makes us feel safer in a place that has a lived in look. And While the Potter future is possible, I suspect it would just be a short lived fad.
