You've perfectly captured my experience as well, I typically only trust it and have good experiences with LLMs when I have enough domain expertise to get to at least a 95% confidence the output is correct. (Specific to my domain of work, I don't always need "perfect"). I also can mostly use it as a first pass for getting the idea of where to begin research, after that I lose confidence that the more detailed and advanced content it is giving me is accurate. There is a gray area though where a domain expert might have a false sense of confidence, and over time experience "Skill Drift", where they lose expertise because they are only ever verifying a lossy compression of information, rather than re-setting their context with real world information. I am mostly concerned with that last bit.
