It's extremely useful for my work.

I have a background in physics but my day-to-day is in software these days. I know just enough to be dangerous, but I'm first to admit that I'm no expert and have no formal training. I am no software engineer. What's worse is that I'm part of a small start-up company and I'm the only person who has any coding experience whatsoever.

ChatGPT is extraordinarily useful for filling the gaps in my knowledge. For example, just now I wanted to explore introducing some module testing into my code. I gave ChatGPT a snippet of what I've been working on, and asked it how I might go about developing some tests. Bam! 5 seconds later it gives me something to work with. That would have taken like 30 minutes if I put it together from Google searches etc.
