Yeah, and in this case, what language does help? Unless there's a call to action in the error message, I don't care if someone told me I broke the Internet, there's a picture of a whale, they tell me it's awkward, or if completely neutral language is used, none of that really makes me feel better about or helps me in my situation.
But having cutesy error messages shows a complete lack of empathy for your users.
Better to just communicate that there was a problem, and if you need to say anything else, maybe just a short "we're sorry, but there was a problem completing your request."
Obviously more helpful information is better, but making light of your customers' stressful situation is the opposite of helpful.
Of course, that's not the case, and all sorts of errors get through, but they find them and put in fixes and don't update the "way" errors are displayed.
It’s not the job of the software to make the user feel better or be the user's friend. It is the software's job to accomplish a task effectively or to communicate why it can’t.
Maybe some day we can have NN and LLM friends in the style of Blade Runner’s Joi - it would certainly be an interesting future to think about. Until then, software should focus on its core purpose, which is certainly not friendship with the user.
