Podcasts allow deep dives into topics not covered elsewhere—as well as points of view not available through “mainstream” outlets.
Here is one example—a brief series but imho outstanding work that would be banned everywhere from universities to mass media:

Here is another example on the topic of UFOs—one of my favorites:

My son(the Scientist) loves to listen to The Lex Fridman podcasts.
He does the deep dive into a lot of tech subjects. Frankly, a lot of the subjects are over my head. Although he gets interviews with people like Netanyahu that others can not.
Keep in mind, Lex has a PHD in Computer Science from Drexel. He is currently employed at MIT. Fridman holds a first degree black belt in Brazilian jiu-jitsu. He lives in Austin and is good friends with Joe Rogan.
