I thought this was pretty huge. Just to have a CEO of one of the biggest Wall Street institutions to not instantly dismiss Bitcoin and crypto currencies in general. He admitted he doesn't have a good understanding of the technology. And I'm sure he would admit he has a bias to the old and current system. He also acknowledged the term "consensus" and it's not such a crazy idea to maybe one day have a coin or money who's value is decided by the people who transact in it, not by a government that says "This is worth $1 because we said so."
