I'm equally concerned that you think that knowing
answer to that question constitutes anything more than
trivia that's even less useful than knowing cartoon
characters. Utterly useless even to the knighted who
already have what they came for.
I think the point was that people think they know the answer when
actually they don't. Not knowing something isn't a problem, you can
just look it up if you need it. Not knowing something but thinking you
do is a serious problem because you never think to look it up.
