I agree with you that "true personalized search eludes them because they don't have enough data from you to tune up a model for you". That's what Larry Page said as well "Google doesn't know what you know". His ultimate goal is Answer Machine powered by AI but that's not happening anytime soon. I think internet search engines that we are using today are primitive compared to what we will have in the future.
