The restructuring and refocusing you described is absolutely necessary, but it's not going to happen under Pichai. All of Google's cultural problems festered under his watch. He should have addressed these things years ago.

Getting rid of Pichai is only half the battle. After they get rid of him, the board of directors then needs to hire someone who can actually lead the company forward. More competent than Pichai may seem like a low bar to clear, but leading a multi-billion dollar company like Google is not an easy task. Developing new market strategies at that scale takes vision and a real tolerance for risk.

So firing Pichai is necessary, but not sufficient, for Google to fulfill its potential.
