The document discusses how the potential future development of artificial general intelligence, known as the singularity, could impact libraries. It considers ideas from science fiction works that envision a future where machine intelligence surpasses human intelligence. The singularity may lead to technologies that vastly enhance human thinking abilities. This could mean that libraries transition to being repositories of older technologies, havens for people who do not use intelligence amplifiers, or even become obsolete if money and jobs are no longer needed. The impact on library budgets is unclear in a post-singularity world.
