I was tempted to agree there -- but that's the thing, whatever comes along and replaces Google won't look like Google, and we probably won't even notice it happening. I don't think Wolfram Alpha is that. I think its goal is honestly too ... computational, logical, factual ... to have the broad appeal of Google. But I don't think that because something is fundamentally different than Google means that it's not the fabled Google killer.
