Had you heard about Sergei Brin obsessed about speed of page load on Google and could accurately tell how many seconds passed to a decimal? I'm using Google Music on iOS. It is by far the slowest app on device, sometime literally taking half a minute to perform an action. This was the time I realized billionaire founders must have left the building and Google is not what it used to be. Sure enough, I recently read article that Page and Brin went through divorces of their own, now spending lot of time staying out of the office basically leaving the company on auto-piolot. Pitchai et al may be good managers like Ballmer & Cook but they are far from visionaries. Fortunately AI is rising and search would be the biggest upcoming disruption.
