I only discovered https://notebooklm.google.com/ today, as an experiment i threw in a dry EU directive, https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CEL... and got it to generate a podcast that was 20 mins long and was a good intro to the directive and natural to listen to. It won't replace podcasts that require creativity but as a tool to summarize info into a digestible format I'll most definitely be using it again.
