But in fictional worlds, we can control technology again. While science fiction has provided the scripts that many technologists have used to create our disappointing future, it also plays an important epistemological role in the struggle against racism, sexism, ableism, classism, xenophobia, and capitalism. It invites us to consider that the ways societies are organized in the here and now are themselves contingent fictions. Science fiction reveals that the social facts many have taken for granted — things like gender, race, sex, class, hierarchy, and domination that are often attributed to “human nature” — are not inherently true and could be otherwise in the future. Technology can be distributed through non-hierarchical economies and social structures. And by describing in detail the potential technologies that could undergird different forms of life, science fiction demonstrates how versions of society where biology does not determine social worth might become durable.
