Since I'm using D for most of my coding projects, Copilot is mostly useless. I can do boilerplate stuff with metaprograming way easier and at a way more consistent pace, not to mention it's easier to modify. And at least ChatGPT, does not know what to do with D attributes, and just randomly puts them everywhere for functions, since it's way less of an AI than how tech people try to sell it (statistical probability based on Markov chains and some small context windows rather than actually understanding what it does).
