I don't have it write my day to day code, because that's complicated and usually niche enough that it's not likely to give a good result.
But it's awesome for something like writing a quick and dirty shell script. most recently I needed to bulk rename 50 or so files with an interactive piece for a special case. I described the operation to GPT and it spit out a nearly perfect shell script. Could I have written the same script in half an hour? Yes, but it was sure nice not to have to.
I also like it for just bouncing around an idea. Recently I was thinking about writing a program to make a midi device from a guitar hero controller, and I was able to get a good sense of the available APIs / libs in a few different languages with a 3 minute back and forth with GPT. Again, I could have easily searched around myself and come to the same answer, but removing the friction is pretty nice.
