I've listened to this podcast episode 3 times,  and often reposted to Jeff's other video interviews  I've been surprised at how slow my mind is to grasp the concepts.  The first time I listened I had a sense there was something important that I didn't quite grasp.  So I resolved to listen again until I got it.

It really is a paradigm shift.  And - as Jeff always says - of Bitcoin remains secure and decentralized, the world is going to change.
