AI promises to be a master technology that can solve any problem—including the problem of death. There are two main contemporary narratives describing how AI might achieve this: cyborgization and mind uploading. This chapter focuses on the latter. It examines how works of nonfiction by influential technologists, in particular Hans Moravec and Ray Kurzweil, have framed this possibility. It pays particular attention to three narrative elements: the promise of boundless wish fulfilment, the assumption of exponential technological progress, and the assumption of personal survival through the mind-uploading process. It then examines how works of fiction, including those of William Gibson, Greg Egan, Pat Cadigan, Robert Sawyer, Rudy Rucker, and Cory Doctorow, offer problematized accounts of these claims. It focuses on three problems in particular, which I call the problems of identity, stability, and substrate. It concludes that science fiction offers a particularly important site of critique and response to techno-utopian narratives.
