It's useful
I have friends who want to dream up a few words for a marketing campaign for their web store. After doing this for the 15th time, it gets a bit repetitive and boring. Asking ChatGPT to generate you some spiel for you "Easter Offer" saves you some time, and actually makes better wording that you would on your own (what with it being boring as hell, as you've already done it so many times!!)
Beyond that use (and others like it), I don't see it changing the world in any substantial way just yet.
I might use it to rewrite the summary at the top of my CV, or to put in some nice wording in a job application (I normally just put "See CV") so I guess it adds value. Or wastes someone's time, if they actually ever read that stuff?
Probably the net result with the current iteration is just going to be a lot more wordage.
