I am a sysadmin, I use it to write simple(ish) powershell and SQL - it does this quite well.

I also used it to look at what Azure Components are needed for a specific project by giving it details, it did it better than the architecht that was assigned to this.

We needed another employee, I'm not a person who writes formal job descriptions - but ChatGPT did it better than the IT Recruiter that was assigned to it and they ended up using my JD from ChatGPT.

My job is easier, but stil requires in depth subject matter knowledge to know what you want the tool to do.

Fact checking a comment on Social media or reddit is another good use case.
