Does he really need to be the guy approving bonuses to employees and coordinating details of investments in 3rd party companies?
It seems far more likely that Page is being evasive and doesn't want to give evidence supporting a narrative that Lewandowski was a superstar, Google was desperate to keep him, failed, and this lawsuit is just a malicious and anti-competitive. (Which I don't believe, but I'm guessing that's the narrative Uber would want to create)
You think he has time for every little detail?
If you read page 24, he said it's not unusual for people to be paid $100M. Do you expect him to remember all the people and amounts paid?
That's a lie. Do you really think Google would be paying someone $100M or something close to that and the CEO wouldn't hear of it?
-He does not remember how Project Chauffeur was started.
-He does not know whether due diligence was done when Google made its investment in Uber.
-He does not know whether Waymo is allowed to file a lawsuit against Uber without notifying him.
What is he responsible for in Alphabet then?
