The common trend is that ChatGPT is confidently wrong about things. While it might work for simpler sentences, like you said, its not 100% accurate. So I would just say use it with a heavy dose of skepticism for now (as I am sure with versions 5 and 6 it will be more accurate with time).
Edit: I made a thread to avoid making the same comments in the future with ChatGPT
I think overall I would just emphasize for people to check their work. Think of ChatGPT like a calculator, the answer might be right but the inputs that got you the answer might be leading you astray.
