Having super technical info about any system is good... just read your audience. Yuppie buying a posh new condo probably doesn't understand or care.... all he needs to know is that it can cut off power. If nothing else, get it stuck in his mind where it can be reset and where the 'afci info sticker is' - usually on the panel.

The retired engineer/scietific type will love the technical story. After learning the technical info getting into this profession the best thing you can do is learn when to use it.
