As a genre, science fiction is often misunderstood. Behind the cool gadgets, far-off worlds, and post-apocalyptic sorrows often portrayed, science fiction is always a commentary on the current social paradigm. As author and historian Jill Lepore says, "science fiction is not fundamentally about the future. It really is always about the present or about the past. So to read it as a manifesto for the future is to begin by misreading it."
