I believe AI is best used for processing a huge chunk of repeating data, that's definitely where it excels. Also not half-bad for programming, but it'd probably make spaghetti code in the long run.

Good for saving hours on a task that anyone can do but nobody wants to do, but it's not reliable enough (yet) to do tasks that people actually STRUGGLE to do. I could ask AI to arrange my Excel spreadsheet and it'll do it completely fine, I could also ask AI to program me a rudimentary script on Python that does something very specific and small. Ask any more or less, and it'll barf up a random answer confidently.
