I don't think cyberpunk was ever really intended to be proper science fiction. It's more of a fantasy universe extrapolated from 1980s tech. Which is probably why it remains a popular setting today without huge changes - see for example the Netrunner card game. There was even quite a lot of vocal disappointment from fans when wireless networking got added to the fourth edition of Shadowrun. Cyberpunk works quite well as a self-consistent setting, regardless of modern technology.
