I just finished reading William Gibson's Neuromancer. Not the first Gibson I've read. I'd previously read The Difference Engine, which he wrote with Bruce Sterling and which formalized steampunk fiction. Also The Peripheral. But Neuromancer is the one that kicked things off from him.
It's definitely influential. The seedy Pacific Rim setting, for one thing. The girlfriend who has herself programmed with kickass martial arts moves. Something like The Matrix movies wouldn't be imaginable without this book. A lot of synth & samples musicians have paid tribute to Neuromancer as well.
And Silicon Valley has done their best to make this world real. Well, the villains in the book live pretty high off the digital hog. No wonder someone wants to emulate them.
