In 2026, AI world models are expected to revolutionize storytelling and interactive experiences. Tools like Marble and Genie 3 can already create 3D environments from text prompts, allowing users to engage with these spaces similarly to video games. Emerging genres, particularly "generative Minecraft," will let players collaboratively build virtual worlds by using natural language commands. For example, a player could instruct the game to create a paintbrush that turns everything touched to pink. This shift means not just individual games will emerge, but a whole new category of generative experiences, including horror scenarios or endless fantasy adventures. The impact extends beyond entertainment. A new digital economy will arise, where creators can profit from building and selling interoperable assets or guiding newcomers. This offers vast opportunities for income generation and collaboration. These generative worlds will not only serve as unique storytelling mediums but also become essential training grounds for AI agents and robotics. The concept of a multiverse, where experiences interconnect, allows players to explore as tourists or become creators themselves, further blurring the lines between consumption and creation. The excitement around these developments is palpable, with a growing interest in building new interactive experiences tied to the evolving landscape of world models.
