Dunno. I loathed Neuromancer; it's one of the books that turned me off science fiction forevermore, really (or at least until I find someone who actually writes the stuff once again where characters overcomes the technogeekery).

There's something "innate" in a received-wisdom sense that I'm supposed to be getting from the reference about how best to end a book, right?

I don't think so, but then, as noted above, I may well be (probably am) bringing my own baggage to the table. As we all do, natch.
