Wow it already seems like he's completely regretting the decision to post the manifesto. He managed to stumble through the question about whether or not it was a good idea and he said something along the lines of "I think I'll be able to look back at this one day and be proud."
Where did all the self righteous hubris go in less than 16 or so hours? He knows he handled it poorly, and he's coming off as a jilted kid who didn't get a scholarship in the interview. Feel bad for him ultimately though, he is going to live with a lot of regret from this.
Edit: Update, "There is definitely a chance this turns out worse than I hoped for."
Durrrrrrr, you don't think?
