Google has employed a futurist who perhaps ties in nicely with this topic:
Ray Kurzweil (the "Singularity" guy) joins Google [arstechnica.com]
I'm with Tedster on his idea of Google's mission. Maybe they will need external commercial sources for info, or the net at large in order to continue providing a useful front-end-with-ads, maybe not. Freebase/knowledge is good for facts, but to be fair the explosion of sites over the past few years has been more social, or that of opinion.
In the end, there will always be a need to search for information online, and there will always be a need to connect with someone/something outwith Google.
