It sounds crazy, and it’s not a standard idea to envision the future of websites like this. However, actually, this could happen. We already have results where you don’t need to click in order to find the answers you need. Featured snippets are a great example of this.
From the new SEO perspective, that’s really annoying. If you are #1, you may lose traffic overnight because Google has a new idea to experiment with. If you are a searcher, you don’t want 10 results. You want one right answer. This is potentially a good user experience.
