There is no “sort by accuracy” button in any podcasting app, nor are they peer reviewed.
Furthermore, podcasts are not a review of the body of knowledge on a subject; they’re often a complete layperson interviewing a single member of a given field, at best. Almost never do the views of any individual actually represent any field as a whole.
So once we’ve thrown out the concept of accuracy and completeness, ChatGPT fares exceedingly well in comparison. You’d do much worse than ChatGPT for idle conversation level accuracy.
