Google is absolutely not going to start taking more risks. They are at the part of the business lifecycle where they squeeze the juice out of the cash cow and protect it jealously in the meantime. While Google gets much recognition for this research, I believe they are incapable as a corporate entity of creating a product out of it because they can no longer capable of taking risks. That is going to fall to other companies still building their product and able to gamble on risk-reward.
