It's more like an incompetent goofball government. The protagonist is kind of an old post-hippy and not a young "punk." I'll grant the computing. But the idea that Rucker is "far more important" than Gibson - in an objective "influenced most people" sense is not at all defensible. In a "quality and intellectual content" sense, maybe, but Sterling is more important than both put together in that sense. And
Software came out "years" before
Neuromancer only in the most literal sense: two years. But "Johnny Mnemonic" came out the year before
Software and "Burning Chrome" the same year as
Software. But then again, Rucker had published a fragment of a novel and one story by 1980 (though I don't know how relevant the story was and the novel wasn't especially cyberpunkish. And then again-again, Gibson had published a story by 1977. And Sterling had published a story and novel by 1976 (though, again, not especially relevant). Talking priority isn't especially useful with a bunch of people who basically knew each other and were contemporaries and were just part of something in the air.
That is the funny thing about cyberpunk, though. I've said this before but I love the editorial comment (forget who said it) about how "it takes more than two people to make a movement."
Mirrorshades (1986) includes Bruce Sterling, William Gibson, Tom Maddox, Pat Cadigan, Rudy Rucker, Marc Laidlaw, James Patrick Kelly, Greg Bear, Lewis Shiner, John Shirley, and Paul diFilippo. Paul di Filippo was so new that he's already basically "post-cyberpunk" (and tried to invent "ribofunk" years later), John Shirley (speaking of hugely influential people that the general public is insufficiently aware of) was proto-cyberpunk, having been publishing since the early 70s and being far more "punk" than all the rest put together. Lewis Shiner was only fitfully cyberpunk and, like Maddox and Laidlaw, did not have a career that really sustained its start. (Laidlaw now does military SF for Baen, I think - no clue what Maddox is doing.) Greg Bear is as pure-quill old-school SF as you can get - being Poul Anderson's son-in-law is actually symbolically significant. James Patrick Kelly (like Michael Swanwick with
Vacuum Flowers (1987)) wrote an extremely cyberpunkish story sequence but was as "Humanist" as you could get. Rudy Rucker was a gonzo metaphysical mathematician. Pat Cadigan had yet to publish a novel (her first "novel" (1987) was a fixup and tangentially cyberpunk but her later novels (1991+) are determinedly cyberpunk) and her short fiction involved old ladies meeting aliens and magical entities as well as the occasional "Pretty Boy Crossover" and (included in the anthology) "Rock On."
So, yeah, that's true original cyberpunk: Bruce Sterling and William Gibson. Bruce Sterling's fiction (beginning with the post-Delanyesque but embryonically cyberpunk
The Artificial Kid (1980) and the Shaper/Mechanist stories (1982+) and Gibson's were turned into a movement by Bruce Sterling's non-fiction (
Cheap Truth, etc.) and Bruce Sterling's anthology "proved" it was even a
large movement.
To wind back around to the topic: either way, we again see a lot of people and a lot of works and a lot of history and not any one big moment of a single "trendsetter."
