This stategy may prevent Google from ever evolving to concept Search or Latent Semantic Indexing - it appears that Trust Rank and PageRank and Click Popularity will be their focus, as long as the current Algo Technology is being used.
Could any advancements in their Algos be possible - there has been a general concensus among Webmasters in Forums, that their Relevancy has Decreased in the past two years.
Could this Algo technology have gotten to the point where it can not be improved.

How do we find pages that contain the user's query? Let's return to our civil war example. The word "civil" was in documents 3, 8, 22, 56, 68, and 92; the word "war" was in documents 2, 8, 15, 22, 68, and 77. Let's write the documents across the page and look for those with both words.
civil 3 8 22 56 68 92
war 2 8 15 22 68 77
both words 8 22 68
Arranging the documents this way makes clear that the words "civil" and "war" appear in three documents (8, 22, and 68). The list of documents that contain a word is called a "posting list," and looking for documents with both words is called "intersecting a posting list." (A fast way to intersect two posting lists is to walk down both at the same time. If one list skips from 22 to 68, you can skip ahead to document 68 on the other list as well.)
