I know you already say that is your point of view, but I think this very much in the eye of the beholder. I very much like this personalization and it makes it easier to find things I'm looking for. E.g. when I search `latex` I don't want to find latex bodysuits, I want results about LaTeX and I expect Google to know that.

That said, it would be nice if there was an easy way to turn off this search personalization on a search-by-search basis in a similar manner to how one can look for results from a certain time period
