A multitude of AI characters, numbering up to 1,000, have adapted and flourished in the Minecraft universe, engaging in various activities such as establishing professions, sharing memes, and voting on tax reforms. This project, led by AI startup Altera, aims to model human group dynamics and create large-scale AI civilizations. Altera secured over a million in funding and demonstrated an AI-controlled character in Minecraft. Their initiative, Project Sid, involves simulated AI agents with complex "brains" that exhibit distinct personalities and specialize in roles like builders and traders. The agents demonstrated emergent behaviors, such as creating cultural memes and propagating a parody religion, Pastafarianism. While the agents mimic human behaviors learned from training data, they are not considered "alive." Altera plans to expand its efforts into platforms like Roblox and aims to create digital humans capable of genuine care and collaboration. However, experts remain skeptical about the potential for machines to replicate genuine emotions.
