A member of the Maths faculty was opining to me about an error message that was appearing on his laptop. I explained that he could ignore the error message because it was, in fact, an erroneous error message.
That got me thinking. Is there a word for such a thing? All we could come up with was that it was a "meta-error". It reminded me of a metalworking factory in my home town I always saw from the train. It was called "metaland" with the typography overlapping in such a way that it was "metal-land". But no, not for me. For me it was and always shall be the magical place inhabited by supersets and self-referential entities. I could never shop there because the shop guy would always say "nah, we don't sell that stuff, only stuff that's about stuff." Like going to a bookstore that only has books about bookstores, or a bookstore that only has books about books that are about bookstores.
My brain hurts.
I spoke about this once with a friend. All we could conclude from the exchange was that we were both incurable nerds.
