Eliezer complements Musk on the creation of community notes. (A project which predates the takeover of twitter by a couple of years (see the join date: https://twitter.com/CommunityNotes )).
In reaction Musk admits he never read HPMOR and he suggests a watered down Turing test involving HPMOR.
Eliezer invents HPMOR wireheads in reaction to this.
