Personally, I hate even the idea of an AI made podcast, because to me podcasts are personal and emotional. They're about the individual humans who make them. They're not just a source of "information".
I've always absolutely hated the focus on the individual humans and their personalities behind the podcast, and wished they'd be a better source of well-structured "information".
I never listened to a podcast I didn't get frustrated with, even at 2x speed. These NotebookLM podcasts have been exactly what I've always wished podcasts were.
I may have to re-task my paperclip making AI on generating podcasts...
