This is it. If you let the machines do their thing unsupervised, you're creating an optimisation game someone is going to win.

I honestly believe the only way for a search engine to be as valuable as Google was years ago is to let human knowledge drive more decisions. Maybe closer in spirit to what a web app store would look like, or closer to the categorisation Yahoo did. Not to browse by category (though even that would be refreshing at this point), but to better select the most relevant search sources.
