I find it hard to believe that ChatGPT is useful beyond trivial things or giving you a lead that you can follow on Google. It's very frequently just plain wrong.
Well even wrong answers have utility in a forum. When someone posts a wrong answer on Stack Overflow, Reddit or in real life(?), it baits a bunch of replies describing in detail just how wrong that answer is.
ChatGPT has the user interface of an oracle sitting alone in a cave in the mountains, but it isn't as accurate as an oracle is expected to be. That makes it useless to me.
And yes, often I do follow up google searches for some things - but it has already saved me days of research time compared to Google
