“Science fiction is the arena of the not-yet, and every science fiction story has this element of not-yet-ness — usually a bit of technology or a scientific discovery that we don't know about in the real world of the present but that might be a possibility in the future.”

“Sometimes people say that we're living in the future, and time's up for science fiction, but I think that never will be, because science fiction really isn't about the future. It's about change and present-day concerns”

“Accurate prediction of the future, of its technologies and traumas, has always seemed to me to be the least interesting thing about science fiction. The Killer Hook.”

“Science fiction writers, I am sorry to say, really do not know anything. We can't talk about science, because our knowledge of it is limited and unofficial, and usually our fiction is dreadful.”

“I stoped reading science fiction once I saw that the UFO was real. It became science fact that just hasn't been proven yet.”

“Science fiction inspires scientists, but it doesn't exist to dictate what our future should look like. Great science fiction is fun to read and it makes you think, period. Claiming anything more than that is dicey. Grand visions of the future were more prevalent in the golden-age science fiction, but all fiction is a reflection of the current times. As science moves more quickly, the horizon of science fiction tends to recede closer to the present.”

“Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.”
