I'm not personally shocked by things he says, I just think he's not particularly smart and I think he tends to have the same thought processes happening over and over again, which weren't particularly more than sophomoric insightful to begin with.
At best I think he might be useful to discover interviewees that actually have interesting things to say and go from there.
What I am shocked by (and I suspect this is the shock people mostly have) is how some people are like, Joe Rogan fans. Like the article author here. To the point he's the one guy he mentions in the article. He just not that interesting!
