I agree Connavar - see my post above. There's a broad panorama of writing classified as science fiction. (Indeed, it's quite difficult to define science fiction.) Some is more focused on ideas common to mainstream fiction, some is more far removed. Dystopian SF is still (just about
) about tweaking reality.
Ian - we must be talking at cross purposes, apologies. My definition of futurism seems to be different from yours. I agree science fiction is not about future studies and predicting what future technology will actually look like, if that's what you're saying.
