When more than 1 person is speaking it feels like making sure the listener awareness and information about the topic is not the priority, while podcasts where 1 person is speaking, prioritize the listener as the top priority with higher ability to explain and inform.

I know that interviews and talks is one genre of podcasts, but I feel like they should not exist as they are very illogical in order and they seem to not inform, educate or entertain probably.
