ChatGPT is good for some things, it's not very good for others. If you're writing a paper on a controversial topic, you're going to get a one sided and biased answer; and it will be written like a HS freshman. If you're asking something straight forward, you'll have a better experience. Some people have said they've gotten it to diagnose something, but I've tried and failed at getting it to do such a thing. I do think there is a massive over reaction to its usefulness, but it is a powerful tool to have, nevertheless.
