From what I have seen, there is no guarantee for correctness on technical matters.

But it comes close, which makes it a useful tool. A programmer can get it to generate some code, then they go through and make sure it's good. I've used it for that, there was one problem it wasn't able to help me solve, but there was another problem where it probably saved me a good hour or two (probably more if I lost focus because of untreated ADHD) of trying to find if someone else had my specific problem or else breaking the problem down to more generic problems.

Similar goes for art. Artists can use an AI generated image as a base and work from there.
