I agree with Pratap. You cannot trust ChatGPT answers, you have to know the answer yourself in order to check if chatGPT got it right; in which case there is not a lot of point in asking ChatGPT.
It is very good at summarising text, or expanding on an idea. I use it to write computer programs. It does that a lot faster than I can. I can then just test the program rather spend ages typing it. So it has it's uses, but it needs to be used with care.
