Wait, our CEO has a vision? Google company culture strongly erodes for two reasons: De-facto retirement of Larry and Sergey and significant deepening of the reporting structure in the last few years (ie endless layers of middle management). Both of these make consistent vision and values much harder to achieve. Recent Googlegeist just reflects that.
Honestly as a Googler I neither saw nor needed the vision of Larry, Sergey, Eric, Sundar, or anyone else except maybe Urs, Jeff, and Sanjay. I mean I worked on the C++ toolchain. Making a bitchin' compiler is its own reward. I guess things are different on product teams?
Business is complicated. You cannot be narcissus forever.
