Who defines what words mean? The people who created them, or the people who use them? I can't see any pressure to reverse the trend shown in this video, and so I predict that "browser" will come to mean a search engine (but don't worry, there will remain a vestigial secondary technical meaning of, a kind of software application for accessing the web.) But it does illustrate Chrome's positioning challenge: how can google have a browser, when it is a browser?
