In a good and entertaining way, podcasts rely on sensationalism and cherry-picking the juicy info.
I disagree. It's very difficult to sit and bullsh*t a podcaster to his face for three hours straight without tripping yourself up at some point. For a few minutes, sure, but three hours is a Herculean challenge. We also have the advantage, when the podcast is in video form, of reading facial expressions and body language to gauge credibility. Furthermore, the comment sections at those sites allow the viewers to immediately discuss any lies or contradictions, so debunking happens essentially immediately. Long-form podcasts are one of the better vehicles we have for quickly sussing out the poseurs and charlatans.
The "sensationalism and cherry-picking" you mention is what legacy media do. It's the stuff of newspapers and television, not unedited long-form podcasts. I'm old enough to remember
stuff like this (which was only debunked because GM had deep pockets and a whistleblower and was able to gather forensic evidence from junkyards; most media lies go unchallenged due to the expense and lack of whistleblowers and available forensic evidence).
Non-fiction books are extremely valuable and irreplaceable, but that's only the case if they're factual and written in good faith. An awful lot of "non-fiction" is in fact nothing but convincingly-told lies--I mean, for almost any polemic, you can find another book taking the opposite position, and they obviously can't both be true--and the format doesn't lend itself to immediate pushback like podcasts do, and that's a weakness of the format.
No, I think podcasts are a superior format for disseminating information, and I think they're here to stay until the government decides to censor--I mean, "regulate"--them in order to protect their corporate, NGO, and foreign friends and prevent their own dirty laundry from being aired.
I still love reading non-fiction books, by the way. For example,
The Mutiny on the Bounty and
The Ballad of the Whiskey Robber are highly entertaining and utterly fascinating, and I'll recommend them to anyone. I learned to play the banjo from reading how-to books. I gave three family members non-fiction books--two how-to books, one sports-related motivational book--for Christmas just a few days ago. And I've read plenty of more scholarly things, too, in the fields of politics and philosophy and history and economics. I obviously value that stuff. I simply recognize the format's limitations, that's all.
