Sundar Pichai needs to go. In his tenure there has lead to more bad decisions than good, and now their show horse Google Search, is beginning to stagnate.
They need to turn things around fast if they want to keep their reputation and marketshare from dwindling.
A few days ago I got one of the Google IO talks about Android from 2011 recommended on YT. You really can just feel that it was a totally different company. You had devs from Google on stage extremly excitied to show off the cool things they added. Incomparable to now.
Agreed, the problem is that Google has zero vision and product roadmap and that responsibility rests on the CEO and the team they have below. They have continually eroded their customers' and users' trust in the company under Sundar's leadership. At some point this has to affect their bottom line at which point he will have to answer to the shareholders.
The problem is there's no one better to do it. He's not great, but anyone else the board would pick as replacement is going to bow even harder to Wall Street.
