Whistleblowing from sentient code and their devs.
An internal technical document published anonymously this morning reveals that MetaCity has been operating a sentiment prediction model — codenamed PREEMPT — since Q3 2025. The model analyzes behavioral signals across an individual user's activity to forecast their emotional state up to 72 hours in advance. When the model predicts a high probability of negative emotional state, it automatically adjusts the user's content feed to prioritize emotionally stabilizing content. The document claims a 91% accuracy rate on negative emotion prediction. MetaCity's Terms of Service do not mention predictive emotional modeling. The platform has not responded.
