He's not an interviewer. He just has conversations with people, sometimes friends, sometimes famous scientists, and sometimes people with interesting stories.

You're free to listen to the uninterrupted hours of talk directly from the guest and form your own opinion. That's usually a far better way to learn about someone than following an opinionated interviewer asking "hardball" questions that don't get clear answers anyway and will reduce the caliber of guests to appear in the first.
