Sam 'Half As Interesting' Denby actually did a surprisingly good job explaining
this for the average only-vaguely-technical viewer...

[ For all the bad dad jokes he tells on HAI, he's got really good research
skills/staff, and his long-form stuff on Wendover Productions is excellent ]
Indeed, with the exception of getting the expansion of BGP incorrect, he's simplified it and explained it in a way that the average viewer can understand... He's really good at that, and has done a great job with this!
