watch the segment 3

If you have a moment, scroll to the timestamp where the presenter pauses and says to watch the segment—it's about forty seconds long and really ties the whole argument together. I wasn't expecting the twist near the end, but it makes the earlier points click. Just hit play and give it your full attention; the visuals are subtle, so don't multitask.
