2017 Reprint of 1909 Edition.  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.  It is intended as a chilling reminder of the possible consequences on over reliance on machines and the changes to human capacity and character that could result from this over dependence.  Consider a classic of the science fiction genre and a prescient warning about our reliance on machine technology.
