I'm very interested in how generative AI can potentially be used in video games in the future. Imagine human-like NPCs that seemingly have a mind of their own, and can hold actual conversations based on free-ranging topics you choose talk about instead of preset prompts. Randomly generated worlds based on scraping from endless photographs of real locations or fantasy pictures and piecing them together. Constantly evolving and becoming more life-like/immersive by the day, probably another reason that MSFT is going all in on them.
