So this 'human extinction via VR/fake fitness signals/amusing ourselves to death' thesis - isn't this obviously wrong? Media consumption & fertility are heritable as anything else & respond to selection. It'd require absurdly indefinitely escalating selection to drive extinction.
Extinction by mass VR-induced celibacy argument is plausible given extreme social conditions. Something like Calhoun's mouse Utopia experiment. For now in the realm of sci-fi.
