If that's true, then it's a real shame. I strongly prefer written text to podcasts.
Maybe that's just my own taste, but to be honest, I believe, that it's just a much, much better medium for conveying ideas. With text I can process the content non-linearly. I can skim to get an overview. I can go back to previous passages and find them again easily even days later. I can take more time to reflect on difficult parts and less time for stuff I know already. I can quote sentences easily to share insights with friends...
