Google can't realistically push more people to use Google by default. Google search is a monopoly.

I believe it is fair to state, however, that one of the reasons that Chrome exists is that Google wants Google to be synonymous with the Web in the minds of consumers. When your browser is Google and your search engine is Google, the web to you is Google. This will dovetail quite nicely with all the other places they're trying to expand to once they manage to establish a dominant browser market share.
