The internet evolves and changes, the way that we use it changes.
I too see this as a small step on the way to get people to use Adwords as a way to drive traffic, after all, organic search has a cost too so there is, apart from cost, no difference between buying traffic directly through PPC or indirectly through SEO.
That said, I have a feeling that as we move down the road of internet development and the use of RDF (Resource Description Framework) that search engines as we see them now will become less relevant, we may well end up doing search directly from our browser without use of a search engine such as Google. But that's a whole other topic.
