> It's a false distinction. Google is more than a search engine; it is also an advertising company that incentivizes original content creation.

Obvious straw man argument. Replace word google with search engine.

> Expand your scope to both Google, and the creation of an ecosystem of SEO pages which Google incentives. They are the same, in totality. Google doesn't just index -- it also funds the creation of landing pages.

This doesn't matter, you are mistaking dataset with the model. Search engine will not return to you things that were not in dataset, it will give you many results that you can judge with many points of reference. Language model will return you one answer, answer that could be a correct result that is inside the dataset or could be totally false and incorrect but plausible and you will have no point of reference to check that unless you use a real search engine.
