singularity: Harvard & MIT researchers built 8.3 billion AI personas to simulate the world’s population What do you think? Apparently they've found a way to simulate populations based on persona agents, where they correctly adhered to their assigned traits in 91.5% of trials. Could this help with designing election campaigns, validating products or features without focus groups, A/B testing and all that? Link to the paper: https://arxiv.org/abs/2608.04205
