Somewhat ironically, I think Google's brightest days had Eric Schmidt (MBA, "adult in the room") as CEO.

>Early in his career, Schmidt held a series of technical positions with IT companies including Byzromotti Design, Bell Labs (in research and development),[19] Zilog, and Palo Alto Research Center (PARC).
During his summers at Bell Labs, he and Mike Lesk wrote Lex,[23][7] a program used in compiler construction that generates lexical-analyzers from regular-expression descriptions.
Sun Microsystems In 1983, Schmidt joined Sun Microsystems as its first software manager.[19]
