Eh, that needs qualification to make sense. Just crawling and trivially tokenizing the web counts as "indexing all the individual web pages" but that's never been such a monstrous task.

Having results fresh to-the-day/hour/minute is a better example of something that will probably be looked at is child's play even though that's a very new, very computationally expensive development in search.
