Machine Man

UNDER CONSTRUCTION

Barry, Max. Machine Man. New York: Vintage-Random House, 2011. "A Vintage Contemporaries Original."

Very-near-future or contemporary satire moving into SF themes on prosthesis, in the tradition of, among other works, Bernard Wolfe's Limbo, dealing with cyborg transformation toward the "transhuman," personality uploading into a computer, and other tropes on the human/machine interface and interpenetration.

The protagonist-Narrator is Charles Neumann, Ph.D., whose name may be suggestive for many readers: Charles Darwin and evolution, plus John von Neumann for many things, including what we now call cybernetics and for self-replicating "von Neumann machines."[1] Quoting part of the Wikipedia synopsis,

Charles Neumann is a mechanical engineer working at Better Future, a military research company. After losing one of his legs in a hydraulic clamp, he begins to tinker with leg prosthetics. The replacements he builds are so advanced that he amputates his remaining leg in order to make full use of them. [...] ¶ Over the course of events, Neumann gradually replaces more body parts with machinery, suffering various psychological side effects in the process. After first being rebuilt from the neck down as a machine soldier, his mind is eventually uploaded into a computer.[]https://en.wikipedia.org/wiki/Machine_Man_(novel)
