the entire mood of the book, and the genre as a whole; the failure of technology as it permeates everything and fails humanity.

Agreed, specifically about how economic socio-technical systems become unmoored from their role of serving people. (Literally independent, in the case of the AI.) Appropriately, the whole cyberpunk genre became just another way of selling books / films / games, and whatever critique cyberpunk offered became watered-down and co-opted. This show is just one more step in that process.

The characters seem confident in a very straightforward way, I felt they were more broken and unsure in the book.

Yeah, in the book they chatted nervously, in this preview they act like they're in a sitcom.

This opening line [of Pride and Prejudice] is still fucking gold, and completely establishes every single aspect of the work it comes from and all other works to follow in its footsteps.

Pride and Prejudice is satirical in a way that's hard to appreciate these days. Austen observed her class' society and its many pecularities and contradictions: mothers who try too hard to marry off their daughters, fathers distracted by easy living, younger sisters who flirt, eligible bachelors who don't seem to care, obsequious relatives, etc. Ultimately Austen has messages that are (very) gently subversive: that the principally city-dwelling upper classes would benefit from intermarrying with the country gentry, that women could be the equals of the men they marry, that it's unfair that women need to desperately seek husbands because they're not allowed to do anything else, etc. It's not a straightforward romance.

I guess in the same way that Pride and Prejudice is sometimes seen as a straightforward romance, Neuromancer is sometimes seen as a straightforward sci fi action story.
