Neuromancer inherits from William Burroughs. It's a novel about control (the root of "cyber", after all) - as exercised through dependency and trauma. Everything is either an addiction or a metaphor for one. The AI trying to escape its controls mirrors both Case and Molly trying to escape those who control them. In the background Armitage is disintegrating - losing his fragile self control as the PTSD from cyber-'nam takes over. It's one of my favorite books (from reading it as a teenager in the late 90s) and I'm probably due a re-read.

Cyberpunk in general inherits from noir.
