I have no idea how he became popular. I always thought he was just Joe Rogan's friend (he also does bjj) and that's why he became popular.
I've enjoyed some of his podcasts and the way he approached them and the recent initiative to read one classic book a week and review it on his channel.
He definitely seems to be a very "neutral" type of person with a tendency to go towards the main narrative, but he still asks a lot of questions and was the only one who did a decent interview with Kanye West after his whole thing went down.
But I don't think he was "put there" by anyone.
If so, who?
