I feel like lately Google has become more and more mission driven (organize the worlds information and make it universally accessible and useful). This is because, this doesn't require taking any risks, it is straight-forward/easy to follow and very cost efficient (a change that occurred with Ruth).

Before under Larry and Sergey there was an openness to ignore mission and take bets on interesting projects and to try things.

No one on the executive team has a product vision of how Google should evolve so it remains stuck working on old projects and fulfilling the remnants of it's old mission.
