I'm not the best at speaking unscripted, so I could definitely relate to your awkwardness on the H3 podcast. I find that when I say "i don't know" to something, it's not particularly because I don't know the answer but more because I don't know how to articulate that answer in words. I prefer expressing myself through text because I can usually think stuff through before I say it. Would you say you're the same?
not completely. i am very good at speaking unscriptedly, (actually easier than scripted) but the pressures of having a silent invisible live audience of thousands, who you can't see, made me feel unexpectedly ridiculous, and in hindsight i should have acted more ridiculous, to be more in tune with how i was feeling
