That is one of my all-time favorite youtube videos... This one, and a similar one on unicode[1], are my goto exhibits when I need to illustrate to a non-technical family member how much background complexity is involved in software
I would think the time zone example would go over better than Unicode, because it's less esoteric. Almost everybody deals with time zones at some point; not everybody deals with Unicode.
Surely they do. They're just not aware of it ;)
(Yes, yes, amounts to the same thing. Except when it breaks.)
