Very well written, I like how playfully the author talks about the subject. The metaphors are essentially correct and work to bring the level of technicality down for people who can't spend dozens of hours on the subject. Most of us want to get a quick summary where we understand something when we can't invest the time it might otherwise take to get intellectual gratification.
