to be honest, I don't think this is just a problem with AI. It seems like people create slop across almost any media platform. The number of videos I get recommended of someone breaking a glass bottle on a staircase is ridiculous.
A podcast is basically a list of files which are the episodes (together with episode metadata), so this would presumably fetch those and notify you when there's new ones / download them, and maybe keep track of how far along you're in each episode and provide playback speed controls.
