It's one of the rare use cases where it actually makes sense. If you have, say, a scene where a meteor strikes a large city, if you are an indie shop with a tight budget that's probably happening off-screen or you'll pour 90% of your budget in that one scene and it will still look like shit. Now you can just have an AI generate it, if the scene is isolated enough and doesn't have too many continuity details to handle it will look pretty good for a fraction of the cost. It may be the best example of a situation where AI levels the playing field.

And quite surprisingly, this will probably be more environmentally friendly too because CGI is a big fat energy hog.
