People without sex dolls also have lower birthrates. It's because the time previously used for fucking and childrearing has instead been owed to our masters since before we were born.

the sex doll thing was intended as a metaphor throughout this thread. we've been slaves for thousands of years, that bit hasnt changed. what has changed is that people nowadays no longer care about themselves because they are fried. watching life on a screen feels close enough to the real thing - why bother living at all, living is risky and can hurt you. the usual answer to that would be testosterone pushing us to do risky things, but test rates have cratered. in the absence of risk attraction, values would help, but nobody has any values, because we decided to throw religion in the bin under the expectation that values would spontaneously manifest (which they didnt, no surprise, we are literally monkeys). and after all that, yes we are being worked to the bone more than ever - at least serfs owned their land.

My guess is we'll end up divorcing human reproduction from human sexuality at some point anyway. I don't know if that'll be a net good thing or a net bad thing, and don't have a strong opinion either way, but I do know that regardless of any debate about the causes of low birth rates, we are no longer subject to the evolutionary pressure that, however accidentally, gave us what intelligence we have. (Many of the religions you seem to be advocating would say we never were.)

Anyway, none of this is an emergency. Near-term survival is the real concern, accompanied by continued technological progress. Neo-Luddites are working up the courage to take direct action (see comments elsewhere in this thread), and they will be using tools far more effective than the shoes, angry words, and monkey wrenches their predecessors employed. Meanwhile, the most popular religion in America has convinced its followers that a nuclear war is just the ticket to bring Jesus back.

I wish those words were as stupid as they sound, but we live in times that celebrate stupidity and are ruled by those who embody it. If we can get through the next 50 years without any major civilization-level setbacks, I think we'll be home free. So that needs to be the focus.
