Heavy is the head that wears the crown, and the biggest threat facing Google is … well, Google itself, actually. That’s according to company co-founder and current CEO Larry Page.During a rare public appearance last week (at Google’s Zeitgeist conference, in Arizona), Page said that big companies tend to be slow-moving companies, and that there are “basically no companies that have good slow decisions.” Former chief executive Eric E. Schmidt, joining Page on stage at the conference, concurred, saying “the problems at a company at Google’s scale are always internal at some level.”
