Can't wait for the Onion article proclaiming that Google is discontinuing Google Search. Or will it be an Onion article? Maybe Google will come up with some alternative that can further advance their ad business.
Would a lot actually change? For people doing SEO probably yes, but as a user who switched all my browsers to default to DuckDuckGo some time ago already I think I'd barely notice it (as that switch was barely noticeable as well).
