Pichai has been a very poor CEO but Google's position was so strong that it is still doing fine. I am sure he is in the founder's good graces so as long as the company's stock takes a big dive he is gonna stay at the helm and keep raking in the big bucks.
Pichai has been a terrible CEO, he almost lost the AI race before it started because he was too focused on Google’s consumer products. I was shocked they kept him around. He’s very much just a money manager like Tim Cook or Steve Ballmer. Those types are great in the short term but risk the entire company’s future long term
That's about Google, though. The picture about Sundar specifically is harder to evaluate. The pessimistic take is that Google had that position already and Sundar failed to proactively lead through a fundamental product shift, forcing the company onto the defensive for some time. The optimistic take is that Sundar, having occupied the top spot since 2015, prioritized investments in the company's overall technology development, then successfully executed a rapid product pivot when the market changed, securing a dominant position in both research and product that nobody else can compete with long-term.
