When I use ChatGPT I feel like I'm looking at a different technology than other people. It's supposed to be able to answer every question and teach me anything, but in practice it turns out to be a content-farm-as-a-service (CFaaS?) Copilot is similar, it's usually easier for me to write the code than iterate through it to find the least bad example and then fix the bugs.
That said, AlphaGo went from "hallucinating" bad moves to the best player in the world in a fairly short period of time. If this is at all doable for language models, GPT-x may blow all this out of the water.
