If Google drives the consumer cost of high-speed internet down to nothing in response to the threat of google fiber, then Google wins.

Google wins when people use the web. Cheaper access to high speeds means more users at high speeds. Higher speeds means more pages per unit time, which means more ads server which means more revenue.

Google is declaring that the the US will have higher speed internet if they have to implement it themselves. Bold move. I hope it does drive down the costs.
