A few mentioned already that are great.  Guess I listen to a pretty broad spectrum of stuff.   Jordan Petersen and Lex Fridman have some guests that don't much interest me, but some that are fascinating.    Mike Baker's PDB is a really well done snapshot of daily current events that only takes a few minutes, retired CIA dude.  Dan Carlin has some serious deep dives into history, some of those are pretty dark and long commitments though.
