Having worked on an app that incorporated these kinds of error messages, it's not about bordem, it's about not scaring/confusing the user. "Something went wrong and your computer will restart" is more understandable to a layperson, than "Exception: Segmentation Fault". Usually messages also need to fit within an organisations documented "tone of voice". Personally, my preference is for friendly text followed by technical details.

That one tweet from years where they said they wanted the error message so they could fix it, like, I don't think you can fix the thing a team of 500 people has been working on for multiple years from a JavaScript console.
