Oddly, I get the exact opposite feeling.
> a dark future where computing, communication, and artificial intelligence technologies were dominant, complemented by significant medical advances, large inhabited satellites in Earth orbit, and considerable drug use.
Are not computing and communications technologies dominant now? Are not the advances in AI (having recently beaten the GO world champion) and the influence of AI in our society (Cambridge Analytica, Google, ect) becoming more pronounced? Aren't we making staggering advaces in medicine (even if these medical advances can only be afforded by an elite few - another cyberpunk theme) ? Aren't the Chinese in the process of establishing a moon base with several "megacorps" planning the colonization of Mars in the near future? Isn't drug use extremely widespread (both illicit and "legally" prescribed drugs virtually ubiqituous)?
I would suggest that if you look at where society was in 1984, and look where we are today, we are well down the path towards a future that looks similar to Gibson's vision in many ways - we just aren't there yet.
Cyberpunk dates at least a decade before Neuromancer -- Brunner's Shockwave Rider form 1974 comes to mind (and is a pretty interesting and strangely timely read, given that it is almost 50 years old).
Cyberpunk wasn't coined as a term until right around the same time as Neuromancer came out and Neuromancer swept the big sci-fi awards, making it a fair thing to say that it 'helped to establish'.
Still a great read though.

He also wrote a fantastic, underrated novel that is definitely his most cyberpunk: The Computer Connection (1975), also published as Extro. It's great fun, and at times paints a future even more callous about human life than Gibson ever described (the main character is arguably a serial murderer, even if he has good intentions). The book was poorly reviewed at the time, and I wouldn't mind admitting that it's "flawed", but it's still one of my favourites.
But I haven't been able to find it again. Maybe I imagined it.
I think Shockwave Rider captured the sense of accelerating change and what Toffler called "future shock" (modeled on "culture shock" it's the discomfort from finding yourself embedded in the foreign culture of the future). Vinge anticipated privacy issues (and may other important considerations in his other works like "Rainbows End") and Dick is exploring the nature of what it means to be human.
Gibson's Neuromancer shows a world where extensive body modifications are commonplace, but it does not seem to affect anyone's self-image or concerns about identity. So at some level "Do Androids Dream of Electric Sheep" is more philosophically and psychologically profound.

Obviously, SF involving computers is pretty extensive, and there is a fuzzy line between "cyberpunk" and "this story involves computers at some level." My criteria are: Are computers major characters in the story, and secondarily, are they helping other characters break lots of rules? :-)
No, it doesn't. Proto-cyberpunk ideas existed, certainly (and more than 10 years before Neuromancer; you can trace the roots back to 60s New Wave SF), but the word itself only predates the book by a year. Neuromancer was very much a crystallization of ideas that had been floating around the zeitgeist.
Or 3 years, depending on how you consider it. The word was coined by Bruce Bethke for his short story Cyberpunk, which was written in 1980 but not published until 1983. Gibson began writing Neuromancer in 1981, though it wasn't published until 1984.
Interestingly, the movie Blade Runner hit theaters before William Gibson had finished writing Neuromancer. When he saw the movie, he was afraid people would think that he ripped off the movie's aesthetic. [0,1] Most people would probably assume the movie was influenced by the book, but the movie almost killed the book.

For someone like Gibson, that period was their childhood. They can be forgiven for assuming it would continue to rapidly expand. In the early 1980s, we had the space shuttles going up like clockwork and MTV was using film clips of those big moon rockets as part of their station-identification clips. By and large, people still thought of space as present and future tense. People didn't really understand it as a demonstration of massive budget redirection and military-industrial might, and that nothing had really been done to solve the physics and make space travel a consumer possibility with low marginal cost.
To me, Gibson's later works try to correct that mistake. His focus shifts ever more towards the information flows, power brokers, and large-scale consumerism. He turns away from the military and space age set pieces. He treats weapons more as artifacts and surplus of a bygone era, just as this big nation-state technology must have seemed to him relics of his past.
