It’s sad that the golden age of science fiction has lost it’s way.

Good Science Fiction is really hard to write - Fantasy is less so. The acknowledged masters of the genre - Asimov, Heinlein and Clarke - have all pointed out that when you write scifi stories you must get the science right to get a believable story. Most scifi readers in my experience either are, or border on, being science geeks. And most are well to very well informed in multiple fields. That makes for a tough readership (read scientifically astute) to attract. And we must thank Gene Roddenberry and his Star Trek and related works that have also raised the bar so high in the video arena. Contrast all that to a Fantasy Fiction work where just about anything goes and it is easy for me to understand the lack of scifi books available. Doesn’t mean that I like it though.

BTW - your link to Judith Bermans article isn’t working. I would like to read it but keep ending up at the PopSci site.

I know this happens to be a late reply as i stumbled upon this site by accident, but the thing is, science already surpassed science fiction. One purpose of good Sci-Fi is to condition people for a possible future by confronting them.
But in times where the scientific field has so much going on from Genetics, Nanotech, Physics, Robotics, AI-Research and so much more (which partially has been predicted by earlier Sci-Fi works) there’s little room to look beyond that. We still have to realize the changes these fields confronting us with by living them first, before moving on. People these days rather use pseudo-sci-fi to have some good time, eat some popcorn and cocoon themselves from a more and more confusing scientific world. The question remains though, if Sci-Fi will make a major comeback when in fact reality is stranger than any Science Fiction. CERN is the best example.

Another reason for the lack of good cinematic concepts overall is the triumph of the computer and internet which challenge hollywood as the main storyteller. There are some good attempts of Sci-Fi in the Video-Game medium. (Crysis Nanosuit etc.) And it will continue to evolve.
