One thing about Joe Rogan is that he covers a far broader spectrum of people than anyone else. Who has Alex Jones/Elon Musk/Neil deGrasse Tyson on?
To be frank I find most "robust intellectual discussion" stultifying e.g. hacker news has exactly this problem.
Sam Harris and Tim Ferriss have great long form interviews with interesting people.
Never really paid much attention to Sam Harris so might have another look at him.
One of the most interesting things about Joe Rogan is that he's not a one trick pony e.g. Comedy/Fighters/TV personality etc. I find him more interesting as a result.
Rogan doesn't self-promote on his podcast, and he creates space for his guests to go deep on their specialties.
I agree, but many vocal fans on Twitter and YouTube disagree.
