As a continuation of what I have said in my previous comment, I'd like to suggest, that what google and the internet in general seem to be doing is aggressively providing candidates for inclusion into the local set. And so, by repetition and easy access they, possibly, help enlarge the local set. If technology gets better, then we can imagine a day where the local set more or less overlaps with the super set, and there really is no difference between the two; a fetch from local set and a fetch from the super set take about the same time and so qualitatively 'feel' the same. Our intuition then has a data set (to draw upon) that is immeasurably vaster than the small set of experiences that a single person can hope to acquire. This is a nice fairy tale.
