There are no characters in City of Bits: Space, Place, and the Infobahn by William Mitchell. This book is a work of nonfiction which discusses the impact of computers and technological communication.

One could say that humanity and technology are the characters of this work. Mitchell focuses particularly on how technology influences the interconnectedness of humanity and how we go about our lives. He discusses how communication has become less personal due to the lack of face-to-face interactions. The anonymity of the Internet has made communication impersonal and detached.

Mitchell also explains how communication technology gives people more power. Time of day and location no longer hinder communication as they once did.

Most intriguingly, Mitchell claims society is now populated with human cyborgs, or people constantly connected to a network via electronics. This constant interaction heavily influences the human psyche.
