This paper examines an ideology I call techno-colonialism. I argue that techno-colonialism represents an attempt to selectively reproduce settler colonial practices adjusted to twenty-first century realities. This argument has implications for contemporary settler colonialism, the radical right, and climate change politics. In what follows, I discuss the techno-colonial doctrines of Nick Land, Curtis Yarvin, Peter Thiel, and Patri Friedman. These figures articulate a political theory about exploiting new technologies to escape the state and found new societies. To explore techno-colonial ideology, I focus on Seasteading—the practice of creating floating city-states to colonize the ocean––as an attempted realization of techno-colonial ideals. As I claim, techno-colonialism attempts to humanize the politics of settlement. But I argue that techno-colonialism's ambitions fail, and techno-colonialism fails to create a harmless politics of settlement. I conclude that we should be attentive to the relations of political and economic power in which such exit projects are embedded. Moreover, this paper also promotes our understanding of climate change and the radical right's politics. While scholars most naturally associate the radical right with climate change denialism, the techno-colonists illustrate another possibility. They welcome catastrophe, and see rising-sea levels as an opportunity to start society afresh.
