I think our collective vision of the future is super important, and there’s no shortage of influences: sci-fi movies, ad campaigns for consumer technology, apocalyptic theologies, economic forecasts, etc.—each a form of fiction, each with its own agenda. Literary fiction, as a genre, is (I think) really remarkably agenda-free. It tends to be personal, humane, grounded in real experience. There’s something useful there—or at least it would be useful if, as a genre, literary fiction didn’t totally ignore the future!
I’m overstating for effect, but I really do believe literary fiction as a genre is more backward- than forward-looking. I suspect it believes in inevitability more than contingency. I fear it prefers memories to plans. You know the story: a family secret, buried for years, finally comes to light—of course it does—and leads to tragic consequences—of course it does.
