Is Google really going to take over the world?

Over the last 10 years Google (GOOG) accomplished things that seem unreal. They became a household name, spawned a verb "googled" and in general look to be on track to take over the world. After an IPO at 80, the stock defied all limits and recently closed over $400 per share representing a 125 billion market cap. A lot of people thought it was expensive at its IPO but if you take into account a $6 last year EPS at its opening the stock was trading at less than 13x P/E. While the stock is trading now at $420 and a stratospheric multiple given their potential for growth it could all be justified. I am not writing to figure out whether the stock is worth $400, I do want to point to a couple of facts that I have seen in the recent press that point to a possible change in the principles that guide the company.

We know of a few CEOs like Tyco's Dennis Kozlowski that have been leading flashy lifestyles that lead to the public scandals. Sergey Brin and Larry Page started the company and stuck to simple principles. Their website has always been simple and being super billionaires never were the ones to flash their money. However on November 4th a story in WSJ pointed out the fact that Google owner's decided to buy a Boeing 767-200 to use as a private jet. I am not the one to tell them how to spend their money or question their integrity, but this may point to the fact that they may start enjoying their money a little more going forward.
Than on November 23rd in the same publication a story ran talked about Google hiring practices and tendency to engage into price wars over talent.
Can Google continue to keep its edge? Do they still have the attitude to maximize shareholder's value? Can they continue to grow at an impressive pace? May be this events is beginning of the maturity stage for Google. To justify their current stock price the company will need to earn $25 per share within next few years. Google continues to find new ways to utilize their technology, most recently in digitizing book libraries. However I think their costs will grow faster than most analysts anticipate. For a stock to be a good short candidate, it needs to have a catalyst. May be these recent events point to an existence of one.
