Not sure about physics but I am really looking forward to see games with NPC characters powered by ChatGPT. That would make some game world really deep and involving.
We already went through this with Stable Diffusion - the content it produces looks very professional, but also somehow exactly the same no matter the subject.
ChatGPT also offers a possibility to e.g. have a real bargaining at the shops: "How much is that sword... ".
Thank you for this comment, it really made me happy.
