Maybe recent pages this is true, but in 2013, AFAIK AI was not yet a thing.
But too bad these sites generated by AI are not tagged in some manner. But an argument could be made that these AI pages are reviewed by a person before they hit the WEB. One can hope anyway :)
Let's consider SEO practices as an example. SEO spam probably IS very likely always reviewed by a person before publishing.
It is still biased and garbage anyway, because the reviewer only cares about its effect on affecting ranking algorithms, not the heritage of digital human history.
