"Kirinyaga" is a science fiction short story by American writer Mike Resnick, published in 1988; it is the first chapter in the book by the same name.
Koriba was raised in the mainstream modern world and has several graduate degrees, but came to resent bitterly how "Western" ways displaced African traditions.
A generation later, the residents live as their pre-modern ancestors did, as illiterate subsistence farmers and herders, with no access to or even knowledge of the larger world.
Koriba has a hidden computer terminal and conducts all contact with Maintenance, the agency which operates the machinery that provides Kirinyaga's artificial environment and keeps its orbit stable.
Kirinyaga was written as a submission for a planned anthology edited by Orson Scott Card, entitled ''Eutopia'', in which all stories would be about a group attempting to create a utopian society.
