Oh no, you are wrong. Machine learning algorithms that are used by Google learn by observing behaviours of users and the results of this learning is essentially a black box of parameters and weights for the target function. Certainly they analyze the data and add some parameters manually, for example, manual review process but most of the work is done in the opaque black box. So your statement that "Google absolutely chooses which pages rank highly and which do not according to their own subjective human judgement" is not accurate.

You say I'm wrong but your argument then supports exactly my position. The 'black box' is trained by humans, and it applies their judgments to the pages it processes.
