"The story describes a world in which most of the human population has lost the ability to live on the surface of the Earth. Each individual now lives in isolation below ground in a standard room, with all bodily and spiritual needs met by the omnipotent, global Machine. Travel is permitted but is unpopular and rarely necessary. Communication is made via a kind of instant messaging/video conferencing machine with which people conduct their only activity: the sharing of ideas and what passes for knowledge."
"Those who do not accept the deity of the Machine are viewed as 'unmechanical' and threatened with Homelessness. The Mending Apparatus—the system charged with repairing defects that appear in the Machine proper—has also failed by this time, but concerns about this are dismissed in the context of the supposed omnipotence of the Machine itself."
"Finally, the Machine collapses, bringing 'civilization' down with it. Kuno comes to Vashti's ruined room. Before they both perish, they realise that humanity and its connection to the natural world are what truly matters, and that it will fall to the surface-dwellers who still exist to rebuild the human race and to prevent the mistake of the Machine from being repeated."

A Qutum AGI system could help humanity is several ways, but it could also be used to create an inhumane world.
