I’m not sure if that would be less for an unscripted podcast, but it still won’t be nothing.
Sure, rather than 8+ hours it takes you about 1 hour… plus the decade or two that it took you to get your ad hoc pseudopublic speaking and domain knowledge up to the level where you can produce that amount of content at approximately the same level of quality without previous preparation.
The assumption is that at least part of the panel already have the relevant domain specific knowledge. There is some time investment to re-read and prepare for the discusion of course (plus the technical part of editing etc.). A monthly podcast could be possibly doable.
