I hope that in the future, AI tools like this can assist indie game devs, so somebody with the idea for a decent plot and gameplay can generate environments, some models, and voiced characters with a generative engine. These tools could also be a cool evolution for games that use generated worlds already: think Minecraft but less blocky.
I fear that it will be used by big studios to supplant or replace human talent, leading to endless titles of same-same dreck without the spark of inspiration or uniqueness that a human developer, artist, or story-boarder can come up with.
Or to paraphrase how somebody else put it: "We thought that computers would do the boring or unpleasant work so that humans could spend more time making art and expanding culture, instead the computers are making the art and we're still doing the shit work"
