Is Joe Rogan as stupid as he sounds?

I’ve never listened to or watched Joe Rogan, but I recently read about him in either the Atlantic or Harpers–they arrived the same week, and I can’t remember.  Evidently millions of young men have nothing better to do than listen to this guy.  He sounds like a whiner to me.  He also sounds like a guy who pops off without much knowledge about anything meaningful.  

I’m 82.  I don’t have a lot of time left.  I’m sure not going to waste it on someone like Mr. Rogan.  I haven’t read all the classics, and I haven’t learned Spanish, and I must get my pepper seeds sprouted.  No time for nonsense.
