For the past decade or so, the only critics of science fiction I pay any attention to, all three of them, have been slyly declaring that the Future is over. I wouldn’t blame anyone for assuming that this is akin to the declaration that history was over, and just as silly. But really I think they’re talking about the capital-F Future, which in my lifetime has been a cult, if not a religion. People my age are products of the culture of the capital-F Future. The younger you are, the less you are a product of that. If you’re fifteen or so, today, I suspect that you inhabit a sort of endless digital Now, a state of atemporality enabled by our increasingly efficient communal prosthetic memory. I also suspect that you don’t know it, because, as anthropologists tell us, one cannot know one’s own culture.
