There aren't a lot of highly technical audiobooks or ones that give the same specificity that would be the same as an academic paper

Writing a book takes like 2-3 years on average. Papers are published everyday. Having a cute two-person "conversational chat" w/ audio works for a lot of people vs. just reading a paper. "No benefit" to you perhaps. Don't generalize the lived experience.

It can synthesize and summarize many topics.

For example, I can give it 8 papers on best practices in online marketing, it will turn it into a 20 minute podcast.

There are errors, but also with real podcasters.
