Pardon me if this is a well worn path, but I'm curious to hear what you all think are promising frontiers for science fiction. What I mean is, we have lots of sci fi that is set in space, is about space exploration, etc. So, space is one frontier of science about which people can write fiction. Another frontier is networks and massive computer infrastructures, captured in stories about AI, virtual worlds, etc. These two examples represent areas of scientific speculation and exploration; they are frontiers for research and discovery and so lend themselves to story telling.
But what are other areas? What other sciences point to frontiers that would produce good science fiction? Some of the hard sciences seem like possibilities: biological science is obvious, and physics, too. We can probably also think about examples of fiction centered on frontiers of genetics, pharmacology, and zoology. But what about sciences like chemistry, food science, and botany? What about "softer" sciences like sociology and management? Can you envision good science fiction around those areas?
I for one would love to read a good food science yarn.
