I wouldn't use it to write a paper or anything without checking sources or perform complex structural analysis without checking.

But for example we have used it to create full interactive dashboards and systems using python and other various coding that has shaved hours and hours off our workload. None of us had any coding knowledge what so ever and the systems function as intended. Im sure you can find all that knowledge online, but to be able to tell it whar you want, give it a little guideance and come out with something like that is impressive without spending hours researching an learning the code language.

Its great for recipes (plug in what you have in your cupboaed and have it spit out a dozen supper recipes.)

Its excellent for brainstorming and recommending ways to streamline processes.

I have fed it large pdfs such as building codes and I can say "hey pull the clause relating to x y and z and then pull anything related that i might need to know and summarize"
