I have been happy about 90% to 95% of the time with code that gets spat out by ChatGPT, though I don't fear for my job being taken by an LLM any time soon. It usually gives good insight in to unfamiliar code, or code in a language that I am familiar with but might have forgotten how to use. That said, I don't use it for every piece of code I write. Usually sections where I am exploring an idea.

At times, I need to correct the LLM on some usually obscure detail. It got the memory layout of the video screen on the BBC Micro completely mixed up with the ZX Spectrum, and I had to correct it about five times before it got it, and then it stuck for the rest of the conversation.

I've been on some wild goose chases, where I have fooled myself into thinking a particular approach would work and ChatGPT has been enthusiastically right there cheering me on.

It's like my dog going on an adventure with me, the dog doesn't care about where we're going or what we're doing, it's just excited to be part of the journey.

And in other cases, ChatGPT has been exceptionally useful in pointing out some blindingly obvious mistakes. It is like having a very knowledgeable, but exceptionally junior developer at your elbow.

If you ask the right questions, and don't except one shot questions to provide perfect answers, it works well for the most part.
