I have found no use for trivial stuff as I don't trust what it outputs. If I have to verify its answer, I might as well just research it on my own, it's literally more work to ask and research than to just research

At work, the only use I have found is to provide fake data so I can run some tests as I work on confidential stuff I cannot use directly. For example, they other day I asked for 30 super hero name, last name, gender and DOB table just to pick from. I could easily do it by hand as it does not have to be accurate at all, but it was faster to prompt than to just randomly type and I did not care if it missed the prompt (very rare scenario IMO)
