how do these talented smart people ever expect to transfer humanity if the next generation is not being produced? Or not being produced in sufficient numbers? I don't know what you're talking about. Last I've checked the pressing issue is too many people, not too few - we never had as many humans on earth as we do right now & the global population is still increasing. I wouldn't mind halving world population if it was possible in non-destructive way (and I wasn't part of the unfortunate half).
