For example I wish someone told me about the existence of Miele kitchen equipment before I accidentally rented an apartment of a well-to-do woman. She renovated it for herself but then rented out when circumstances changed.
Similarly it took me a long time to realize just how much better the veneer wood furniture and doors are compared to laminated chipwood. Price is 3-4 times higher but it lasts 5-10 times longer and is much more pleasant to use. Unfortunately you need years to notice such long-term differences, unless someone tells you.
And I'm basically learning to be lower-middle class here. I'm sure there are similar things to know in higher stratas and I'm unlikely to live long enough to find out naturally even if I happen to get the money somehow.
You were responsibile for something, say, child care, and you just decided to go for beer and leave the child with an AI. The house burns down, but because you had insurance you are not responsible. You just head along to your next child care job and don't too much worry about it.
Such writing would give non-standard meanings to signs, or drawn them in non-standard ways, or use entirely invented signs. It would be a puzzle to work out the meaning, and I imagine most people who weren't very literate would be stumped. They certainly stumped egyptologists for a while when the first examples were discovered.
The second-worst part is that we can't call this hypothetical trans-Plutonian planet "Planet X" anymore.
