Lazarus Lake on Conversations with Tyler: https://open.spotify.com/episode/75PyLxu7sZa7GkZtOUI3lJ?si=E... (Lazarus Lake organizes ultramarathons. He's a legend. You don't need to be a runner to enjoy this)

Amir Srinivasan on CWT too: https://open.spotify.com/episode/496WOLb5hZmrcH7vt1OqFq?si=6... (I recall the arguing being fun, but not many of the details)

Carl Shulman on Dwarkesh: https://open.spotify.com/episode/3ij1JOaafeXoqT0m6sXtBl?si=_...

(Carl thinks seriously about how to reason about AI scale-up)

Overall Dwarkesh seems like the most underrated podcast atm, with Conversations with Tyler being the best. I also enjoyed some Sean Carroll interviews.
