I am not remotely worried about birth rates. Every tech executive hyperventilating about it is extrapolating social trends decades ahead, which is the same mistake Erlich made when he published the "The Population Bomb". The total fertility rate has limitations as a metric too (it assumes constant birth timing).

The fact that they do this coercive paternalism on the very platforms that substitute for real life social interaction is very rich to me. I'll listen to them when they divest from the social corrosion machines.

Predicting population decline is safer than overgrowth. Since with low birth rates we know we need substantially higher than replacement rates to make up for the deficit. Which seems unlikely
