There are so many other really good use cases for AI, but human interaction just isn't one of them. And that's okay!

Some AI ideas I think make a lot of sense in a video game off the top of my head:

- Posters on walls

- NPC to NPC conversations (overheard in a bar, etc.)

- Flora/fauna generation

- Loudspeaker announcements

Anything part of story or lore, I'd rather have a team of good storytellers give me what they got.

At that point, why not just have a human write those responses?

Every character using the same three lines doesn't seem like a technology problem. Getting voice acting out of the time-critical path by automating it might help, but I'm doubtful about the usefulness of AI-generated scripts.
