Aren't we overdue some E. M. Forster??
Can I nominate his novella 'The Machine Stops'? (Maybe it's too short.
)
Humanity has moved under ground and become dependant on an omnipotent Machine for survival. One man, Kuno, rebels against this passive existence, warning that this unnatural relationship could mean the doom of mankind.
