I did nearly the same thing yesterday with a project I am working on. I was stuck with something and was ready to hire a freelancer. I thought I would try ChatGPT. It was amazing to watch as it patiently explained the answer. As you said, it got 80% of it right, and put me on the right path. I figured the problem out hours later and didn't have to hire anyone. AI is amazing! It's the same feeling I got when Google first launched and it seemed to read your mind.
