Oh yeah, i definitely hate it when uninformed people try to make podcasts on specialized topics they obviously know nothing about. I went searching for niche physics podcasts (anything besides space stuff please!) And the amount of literal high schoolers and undergraduates attempting to explain things they're years away from even seeing in class is painful, most admit that they know nothing and are literally free-associating over a Wikipedia article. I give them a pass though since they have no listeners and are usually young but...

I exclusively listen to domain expert podcasts. History experts, policy/economics experts, aforementioned physics experts. Literally event i listen to is hosted by at least one person who is a domain expert. They can branch out and interview experts in other domains but there's always an expert. I honestly can't say (besides the high schoolers which i searched out) the last time i've even test listened to a podcast hosted by semi-charismatic article readers.

I'd recommend you search reddit for lists of podcasts in your desired area. App recommendations are all shit and there's many posts out there
