Perhaps you need to first define "innovation" and maybe also rationalize why that view of innovation is the end-all of determining CEO performance. Otherwise you're begging the question here.
Google's stock performance, revenue growth, and political influence in Washington under his leadership has grown substantially. I don't disagree that there are even better CEO's out there, but as an investor, the framing of your question is way off. Given the financial performance, why would you want to replace him?
