Google's 'long term memory' offers lots of benefits too, and 90% of the time, the filter bubble is the correct answer. Like when I search for a particular business on the desktop, and then later I search on my mobile device in Google Maps, and the very first auto-suggest after typing 1-2 characters it the business I searched for yesterday. This is awesome given how irritating it is to enter stuff on mobile devices, especially when in motion, the fewer characters typed the better.
Most of the privacy issues can be solved just by opening up an incognito window. You can choose with 1 stroke whether you want a bubble or not.
