The amount of wealth generation in Silicon Valley (and with telecomm in San Diego) is pretty amazing. The problem with a google or yahoo is that the Really Smart people have really no incentive to stay if they strike it rich. They then have the money and security to move on to a new start-up. The number of old-school googlers that have started new companies is pretty high (just as it was for yahoo). I guess it’s how we, as a country, stay on top of innovation but it makes a company like Yahoo (only 14 years old) appear like a dinosaur.
Of course, folks that move to SD or SF from Texas or North Carolina have a bit of a problem trying to jump into the market versus the option money :(.
It’s amazing how Xerox could have retained its relevance in the tech world if it just was able to assess its own technology–course, we might not have an Apple today.
