Google, whatever the algorithm, is just a spam finder. Failed spam tactics with one algorithm sit there waiting to rise to the top when Google changes the algorithm.
There's just one Google but billions of sites most of which have either accidentally or deliberately skewed their optimization and backlink profile in one way or another.
There are always 10 results in the top 10 and it seems to me that it doesn't matter what Google does half of them will not really deserve to be there and users will be disappointed when they visit them.
