> he knows when to just let the speaker speak

I think similar to Joe Rogan that's the main value he provides to listeners. He identifies guests that have some veil of intellectualism and provides them with a platform to speak.

However I don't think that makes for an interesting interviewer. There are no challenging questions, only ones he knows will fit into the narrative of what the guest wants to say. I might as well read a 2-3 hour PR piece issued by the guests.
