Do I ever wonder why science fiction isn't real? No. I also don't wonder why we don't battle Orcs, have a female president, or fight Pokemon for experience points. Just because somebody can imagine it doesn't make it possible (otherwise, I'd be Spider-Man right now). And even if something is possible, somebody has to figure out how to make these things work.
Look at sci-fi a couple of decades ago. A lot of the things they imagined we'd have a thousand years from now have already become a reality or have become obsolete. Look at video games and how fast they've advanced (graphics, motion controls), look at smart phones and how you can watch a movie instantly or download an app. Look at the internet and nuclear energy. I don't know what you were expecting but if you took somebody from the 1800's and dropped them in Time Square, they'd think the were in the middle of Blade Runner.
