Google Fiber represents the start of the infrastructure part of the new Google Skynet.

Some people see Google Fiber and see it as Google trying to become a traditional ISP or influence the ISP sector. Google Fiber is far bigger than that. Google Fiber will provide the necessary bandwidth for a modern national communication system. By activating and operating FTTN stations and entire cities full of FTTH, the opportunity to broadcast a wireless signal citywide becomes realistic.

The current generation networks currently marketed as 4G (HSPA/LTE) and, along with the previous 2G/3G networks, will be maintained as the legacy/emergency/rural networks. Over time, even the rural locations will be serviced with Google Fiber.

With a high speed, modern wireless network at their disposal, projects like Project Glass fit surprisingly well. No need for a cell phone device to pair your Google glasses, chances are you'll already be within range of a Google Fiber wireless signal and Glass will auto connect and sync with the rest of the skynet. There's plenty of local storage at the necessary scale already using a microsd card - but you really won't need it. Thousands of gigs will be made available and be ever expanding in the same way Gmail's available storage continues to expand for free. If you want more storage, you'll be able to upgrade and pay for more in the same way.

Again, with a high speed modern wireless network at their disposal, projects like fleets of self-driving autonomous vehicles make sense. These cars will take all their individual traffic data / machine learning and send it up to the rest of the google skynet, applying and making the new improvements / adjustments available to the entire fleet. Imagine a system like Uber, but on a national level using automated cars. For unscheduled things, you just put in an order, pick your destination, and a gCar comes to take you to where you need to go. For planned events, you enter an event on your calendar, check the 'travel by gCar' box, and a Google Car arrives to pick you up from wherever you are. Based on where you are and all the other conditions necessary to have you arrive on time, Google Now keeps track and reminds you of when the gCar is close to arriving.

Google expands from being merely a search based business to an modern infrastructure business, growing to a company of which size and influence would make both AT&T and Standard Oil seem meager even if merged together. In Neal Stephenson's Snow Crash, the United States doesn't really exist - it's controlled by super corporations. This look into a possible future appears ever more prescient as the pace in which technology merges with society accelerates.
