Google does a thousand things, but only one of them makes any money -- advertising. If somebody (e.g. Bing) is able to capture a bigger share of eyeballs, or if somebody (e.g. Facebook) finds a way to target ads better so that people will be more likely to click on them, or if somebody (e.g. you!) finds a way to solve the fraudulent-clicks problem (the enormous elephant in the room), then Google will see its revenue stream dry up. And when it happens, it will happen FAST.
