It's more like a pre-draft from what I've seen. But for an area I know, I can absolutely see something like ChatGPT throwing 500 words down on some topic and generating some explanatory boilerplate about something like what a service mesh is. I'll take out some things that I don't quite agree with, give it more of a "voice," maybe add some data/quotes/links/etc.

It's not going to write me something I'll hand to an editor. But for certain things, it could definitely give me a head start relative to a blank sheet of paper.
