Possivelmente Juramento de Fidelidade de Larry Niven e Jerry Pournelle. Há sim uma página da Wikipedia no livro aqui.
In the near future, Los Angeles is an all but uninhabitable war zone, racked by crime, violence, pollution and poverty. But above the blighted city, a Utopia has arisen: Todos Santos, a thousand-foot high single-structured city, designed to used state-of-the-art technology to create a completely human-friendly environment, offering its dwellers everything they could want in exchange for their oath of allegiance and their constant surveillance . But there are those who want to see the utopia destroyed, whose answer to tomorrow's best and brightest hope is mindless violence. And they have just entered Todos Santos.
No entanto, se esta é a referência correta de novos dróides e sarcasmos, existem, mas não há menção de uma droid sarcástico. Um dos protagonistas, Tony Rand, cria robôs que ele chama de R2-D2:
That led to his development of robot probes; small devices with cameras and sound equipment which could move freely through Todos Santos under Rand's direct control. If he sent out two or three of the small tele-operated devices (he called them Arr-twos after the small droid in Star Wars), Rand could effectively be in several places at once, see machinery and construction details in real time from both above and below, and generally explore without leaving his bedroom.
Depois, há uma referência:
"Not those, no. They don't seem to make much sense. News well, mostly in-house news, actually. Even the Tonight Show monologue was pretty cryptic last time I watched. We get movies on the cable," Tony realized suddenly. "That new guy in Star Wars Eight, the sarcastic one who keeps poking holes in Han Solo's physics?"
"Rip Mendez. Mmm. . . maybe. He might go for it. He's got an adopted son."
A data corresponde desde Juramento de Fidelidade foi publicado na 1981 e o livro está definido "no futuro próximo"embora eu não ache uma data explícita. Finalmente, é um livro de Larry Niven (você mencionou que achava que poderia estar nos livros de Larry Niven e Steven Barnes Parque dos sonhos livros, mas eu tenho todos os quatro e não consigo encontrar nada que corresponda à sua descrição).
