I can definitely see it getting used as a tool to flesh out the setting, develop background characters, locations, and giving the universe of a story a sense that it has multiple characters. When enough convincing, you can even get to to put those characters into all sorts of scenarios which it will account for later.

It also does a very good job at pointing out areas that could use more work. I came up with a primer for a story about a space empire at war, and it recommended I expand on the civilization of both the protagonist and the antagonist civilizations, their culture, as well as the history of the war, and the weapons and systems involved.

This is the type of response I would expect from an editor early on into a project.

When you consider that it was perfectly willing to name nearly 40 fleets, create captains for each of them, and give each one a role in the battle line, you get a very powerful tool that you can use to quickly generate a large amount of content that would otherwise be incredibly tedious.

You're still not going to have a great time using it to tell an original story on it's own, but it appears perfectly capable of acting like a mix between editor and a muse.
