Segue - I've used Copilot a couple of times recently and in lots of code output it uses non-ASCII space characters in the code so when you copy-paste working code it still won't work. It's like a practical joke, designed to annoy ... I really can't understand why that would not be immediately fixed. It's very much what one expects of Microsoft, however. Utter insanity.

So how did the LLM not notice when it ran it on his laptop?

We're gonna see this a lot in the future, human beings that gaslight with LLMs other human beings.
