This isn't quite correct. Google may have the best search right now, but its competitors could be just as good and it would still take us a while to find out. That's what happens with momentum. Here's an example: in September 2009 Microsoft released a free anti-virus that was at least as good as its competitors [1]. I'd say its just now getting some traction (and that's with Microsoft promoting it). A small company would take much longer to get traction.
Why do you think no one else can get search right? Have you used other search engines recently? Years ago Google had better results but now I don't really notice a difference in the quality of my results.
