I'm of the opinion that it will require human interaction to fix this. It can't be purely solved via algorithms.
What people don't realize is that the original Google search algorithm, PageRank, effectively looks at how real humans interacted with the websites they were indexing. Only websites referenced by other websites were being considered by Google's search engine. And at the time, that meant real human beings were making those links. This gave them a real advantage over other, purely algorithmic search engines.
Something like this will have to be recreated. We will have to figure out a way of prioritizing search results that real human beings have found to be useful.
