What I'd really value is a podcast powered GPT chatbot, or at the very least, a very good search engine.

Podcasts like Peter Attia's or Paul Saladino's contain so much good knowledge on human biology in the context of nutrition, but it's buried in longform conversations. I often wish I could find a "soundbyte", or in this case, a textbyte. Paul has had guests perfectly articulate the top 10 functions of insulin, or pose perfect explanations for the value of saturated fat and its demonization via the sugar industry. Hell, there is a plethora of knowledge around basic salt that you don't find very easily in Google.

Being able to search for or rapidly recall things like this would be so useful.
