"AI isn't great at creating software, but it is great at writing functions."

This 100%. In my experience (ChatGPT - paid account), it often causes more problems than it solves when I ask it to do anything complex, but for writing functions that I describe in simple English, much like your example here, it has been overall pretty amazing. Also, I love asking it to generate tests for the function it writes (or that I write!). That has also been a huge timesaver for me. I find testing to be so boring and yet it's obviously essential, so it's nice to offload (some of) that to an LLM!
