Science fiction uses the future as an arena to explore and extrapolate from the problems of the present, with technological change and sociocultural change alternating in the role of dependent and independent variables. A broad overview of the trends in 20th and early 21st century sci-fi (or, more honestly, a quick once-over of the books that came to mind when I thought this up in the shower) suggests that the interplay between these variables in our own time determine the predominant “mood” of that era’s sci-fi.
