Academic papers aren't for mass consumption. You can't replace the depth of consideration and knowledge needed to write an academic paper with hosting a podcast or self-publishing a book. Writing for an audience of leading experts is inherently different from writing for consumption by non-experts.

And you can't just equate societal value with "how many people consume it". An academic paper is often as valuable as a tool for crystalizing thoughts in the mind of the author as it is a tool for communicating to the reader.

I kind of feel like you are missing the point of academia.
