I like listening to all the various guests he invites, like doctors or even professional archers. I like hearing them talk about their stuff deep enough where I, as a person who knows not much at all about their specialty topics, can learn something. But it would become not that interesting to me if every single guest of his would dive so deep, I would not be able to understand anything without reading a tons of pre-req material.

It is a really difficult thing to balance, between going too in-depth and being too surface-level. And, I feel like, that's why Joe is so popular, as he nails it very well.

For the topics that I want to dive very deep into, I can just listen to specialized podcasts on those topics. But as a general "seeing tons of cool stuff and learning about basics of really diverse topics I would never see otherwise", Joe's podcast is great. Plus, Joe manages to open up people, to the point where they get really candid and, for the lack of a better word in my mind, human. Even the people who hold very opposing views to those of Joe's.

I'd personally be thrilled if more people were intellectual tourists. In my professional technical life, I'd far rather talk to people with a superficial understanding than people who's mental model is part TV-hackers, part magic.
