The book is a philosophical inquiry into the themes of free will and the value of adversity through exploring a fictional, dystopic world where the optimal decision to every choice set can be ascertained through the use of AI.
The Death of Uncertainty is a story of a world powered by a perfect AI algorithm that can accurately determine what the optimal decision is to any choice one may have — thus, in this world, no mistakes are made and everyone lives the optimal version of their respective lives. One day, a young man of this world stumbles upon suboptimality and adversity, which causes him to reflect on the system, helping him to explore the intersections of free will and uncertainty, adversity and fulfillment, and perfection and human nature.
