Yeah, me too.

The problem is that trying to find guests or, preferably, correspondents is you have to do your due diligence and vet them thoroughly - your credibility is on the line if they turn out to be a charlatan or if they have some utterly dogshit positions because ultimately it can compromise the integrity of the podcast if they host the wrong guest.

Ideally you get a reputable org on the ground to vouch for the person in question but even then you still have to vet that organisation and hope that they'll come through for you.

When you put that fact up against the other fact that the content beast hungers eternally it's no surprise that you get a focus on the settled historical facts and (often pretty vague) general commentary and general statements of position and recounting of the recent current affairs. It's much easier to do that than it is to do the higher-risk, time intensive work of engaging with boots on the ground.
