There's https://github.com/t3chnoboy/awesome-awesome-awesome a meta list of other lists-of-lists. And before anybody gets the idea: awesome-awesome-awesome-awesome already exists.

A set that contains all things must contain itself by definition.

We'll start needing some kind of notation… maybe we'll have to adopt the Knuth up-arrow. Awesome↑↑-list

That would be…awesome.
