I've tried Copilot and to be honest, most of the time it's a coin toss, even for short snippets. In one scenario it might try to autocomplete a unit test I'm writing and get it pretty much spot on, but it's also equally likely to spit out complete garbage that won't even compile, never mind being semantically correct.
To have any chance of producing decent output, even for quite simple tasks, you will need to give an LLM an extremely specific prompt, detailing the precise behaviour you want and what the code should do in each scenario, including failure cases (hmm...there used to be a term for this...)
Even then, there are no guarantees it won't just spit out hallucinated nonsense. And for larger, enterprise scale applications? Forget it.
The EMH is never shown with pips on Voyager. The "ECH" was shown with pips appearing on its first appearance, however:
spoiler
The entire ECH subroutine was created as the result of The Doctor's daydreaming, so the visualisation of a rank appearing out of thin air makes sense in that context.The only other time the ECH mode was used in a genuine emergency (Season 7, Episodes 16/17), he did not have pips.
