On the one hand, Google isn't the best web search tool. I've switched to DuckDuckGo, and so has everyone who's seen me use it. But, I think Google still provides a valuable public service: indexing the entire web and handling that much traffic is not an easy task, and a lot of other things (like DDG) depend on that humongous cluster.
So on the one hand I want to see the best search engine win, but on the other hand if Google goes out of business (or more likely, starts losing money and canceling projects) then I'm afraid it'll take a lot of things out with it, with no clear replacement.
