Manna (novel)  Manna is a 2003 science fiction novel by Marshall Brain that explores several issues in modern information technology, automation and economics, as well as user interfaces and transhumanism. The fictional story is set in 2050 and begins in Cary, North Carolina. The narrator recalls his first minimum wage job at Burger-G fast food joint in the early 21st century, and describes the Manna system, which was installed there as a simple store management tool that guided the minimum-wage workers via headset. He describes how advances in networking, robotics, and computer-vision drove the Manna system to dominate the service industry, leading to mass unemployment and extreme income inequality. After Manna finally takes over his current education job he is forced into a massive, cheaply-built government welfare housing project, with little hope of regaining employment or escaping. After a year in the housing projects he is visited by two women who tell him that because his father bought stock in the Australia Project years prior, he's invited to live in Australia, an advanced society with Universal Basic Income. The narrator leaves the dystopian United States for Australia, and goes on to learn about, and live in, the Australia Project. The novel imagines the future US, which has a libertarian economic system that leaves most Americans are unemployable and living in cramped housing projects, where they are fed and kept safe like farm animals. Birth control medicine in the water prevents them from having children. In contrast, in the Australia Project, everyone has access to the goods provided by automation. "Manna" is meant to be a thought-provoking read or conceptual prototype rather than an entertaining novel ("see exploratory engineering for more on such writing"). The novel shows two possible outcomes of the 'robotic revolution' in the near future: one outcome is a dystopia based around US capitalism and the other is a utopia based upon a communal and technological society in Australia. Essentially, the two differ in that lower-class humans in the dystopic society have been left unmodified and are controlled by AI "managers" to the point of slavery, while humans in the utopian society more directly and efficiently participate in the management of the society as a whole and most or all willingly accept implanted AI aids.
