Much of the "Google is doomed" talk is based on the mere fact that Google is entering these new markets. Getting spread too thin is the fear. Google could focus just on being the best search engine it can possibly be but it's not doing that, it's trying to do dozens of other things too. Some of those things are innovative and cool (self-driving cars!) but other things seem like stupid me-too efforts (everything they've done so far in "social"). Nobody cares about "the potential entry of Facebook into the search market" - that would just be as big a warning sign for Facebook as Google+ is for Google. Trying to do too many things at once is a good way to do them all badly.
