Our current level of technology has brought sci-fi to a weird place. It's hard to make a futuristic science fiction show nowadays because science has progressed beyond the layman. To have a story that expands on our current science, the writer/creator must have a solid understanding of our current technology if they want to make something that is believable. On top of that, you also have to have a good idea of where science will take us and still not rip off something that has already been done. The amount of sci-fi that has been created on the last 50 years is staggering, both in terms of TV and books. I think it is much harder then it used to be, but I also think what is coming out now is a higher standard than what came before it with some notable exceptions, ei Star Trek. Shows like Orphan Black, Wayward Pines (the show hasn't come out yet, but the books are amazing) and Under the Dome show that sci-fi is alive and well but we are not seeing the deep space shows in the main stream the way we used to.
