I did not get the same impression other HN'ers did, I noticed. To me Cory sounded smug and know-better, but maybe that's what I expected out of him. I'll watch it again.
Oh he definitely he sounded smug and know-better, he's a professional TV personality and his audience is not typically hackers. But I think that's more a reflection of him not actually caring deeply about topic more than true conviction. That comment was just a set-up for the truly interesting question.
