The more interesting question is how many multiples of existing growth will it be before Google start to use the data they collect in incredibly unfriendly ways.

How will they push their stock price above $1000? $1200?

I'd like to suggest another metric: September 11s (or "9/11s"). How many 9/11s will it be before Google's reuse of the data they collect is popularly legitimized, in their new role as the nation's biggest defence contractor? This is an insane idea, but I fear not sufficiently insane. I'd peg it at under a quarter of one 9/11.

The company must grow somehow. It must keep growing. As it exhausts its old business areas and sacrifices any ideals it may have once held, you have to at least entertain these crazy outcomes.
