Every decision that we make factors in many variables that are weighed according to how important we perceive them to be. If one coefficient in that "equation" outclasses all others, to a rational person that would become the primary motivator.
>Whether he is motivated by earning a billion dollars over a decade or he’s achieved pure altruism and simply wants to make Google the greatest company in history doesn’t really matter. He can only achieve his goals if he remains CEO.
I don't buy this argument at all. For one, his goals are unknowable and might be what he plans to do with $200m/year, and he could justify anything to attain that $200m up to and including total destruction of the organization. Secondly, many people abdicate power if it's false power i.e. someone forces their hand in critical decisions. He hasn't done that presumably because $200m is more important to him than his pride or (Google) legacy.
