Sexdolls And Reproduction!
One common facet of this is that it's talking about men...men are buying the sex dolls, men are getting "virtual girlfriends", men are going to stop conceiving babies. The ass-backwards thing here is that nobody's talking about women; there have been a few articles about sex dolls designed for women, but they don't frequently go into using it as a replacement for male companionship.
And companionship is always mentioned in the articles, but never really reflected on: the one in the first link basically says that Japan has seen an increase in sex doll purchases as reported loneliness is increasing.
And that's the key to things: men aren't choosing to fuck toys instead of women; they're fucking dolls because they don't have the opportunity to fuck a woman as often as they want. If they find a willing flesh-and-blood partner, they'll be glad to make babies. The guys that explicitly prefer dolls to women, who are most frequently paraded out by 'weird news' interviewers, let Darwin have them. But nobody's acknowledging that if a woman wants to get fucked by a guy they want to fuck, robots aren't preventing that from happening. At least not yet. Terminator-style robots may want to prevent humans from reproducing someday down the road, under orders from the superintelligent raccoons, but for now sexrobots are funtimes for lonely people, not causing a population crisis.
