I agree, I recently found out about Lex Fridman [0] podcast and I am very satisfied with the experts in their field expressing their history and opinions, kinda reminds me of old TED... :)
To me it's been clear that the TED talk format favors good presentation skills above anything else. And I feel it's impossible for the audience to tell if an idea really matters given such a short delivery.
It's much harder to bullshit your way through a 1-2 hour long podcast conducted by a knowledgeable host.
