> You'll find thousands of shows with perfect audio quality and professional-grade cover art that contain absolutely zero intellectual nutritional value

This is why I switched to audio books. Many podcasts with real guests contained too much salad and not enough meat (e.g. a machine learning podcast but they talked about going to conferences).

Contrary to what many think, I believe AI generated content can increase the nutritional value. I've done experiments with turning technical PDFs into podcasts, e.g. summarizing machine learning papers (similar to NotebookLM).
