I think the structure and relations of this bunch of links are a kind of knowledge. And in this information-overloaded age, they are playing an increasingly significant role.
And in the age of artificial intelligence, a lot of problems require a combination of the works of machines and humans. Google can't provide a professional and insightful knowledge structure on its own. But more documents like this one maybe will help a new class of smarter production. Actually I myself am working on the similar production.
Additionally, unlike many extra-long "awesome list", I just pick one or a few links for each nested "category" which are the most mainstream and not outdated, based on the clear trends, public data, and experience. They are not trivial collections.
