Stanford University and Google DeepMind have developed AI replicas that mimic human personality and decision-making based on two-hour interviews with over 1,000 participants. These AI models successfully replicated 85% of human responses in social surveys, though accuracy dropped to 60% in economic scenarios. While the technology offers potential benefits for policymaking and understanding human behavior, it raises ethical concerns regarding misuse, such as manipulation of public opinion and impersonation.
