I find Lex Fridman to be wooden, robotic, non-sequitur, not smooth or charismatic, and (I admit, shallowly) not a pleasing speaking voice to listen to, and not that articulate actually. The main reason he gets famous guests is that he has a reputation for getting famous guests. He's like a Kardashian.
I actively have to tune him out and suppress my wish that someone, anyone else were asking the questions.
But it is what it is. We don't have voting rights on who random walks their way to being famous in this world.
