I've found it great for asking documentation questions. It saves me a ton of time having to search through documentation myself. The problem is when it encounters something it doesn't have information on, it'll just confidently make shit up, and if you're not enough of an expert to recognize when that happens, you can be mislead. It still saves me time, but I use it as a recall tool to get me started when I'm learning to do something new, I'd never use the code it puts out without reading through it line by line. I'm also experienced enough to know when it's wrong and how to refactor its examples. People new to programming could get set down the wrong path by over relying on gpt to teach them.
