Sex robots are far more ethical and accessible than prostitution (of course it would have to be some years from now most likely).
As a technologist I feel obligated to point out that this is far more accessible than most people realize. When people think of sex robots they imagine blowup dolls and the evolution of that. There’s certainly sex androids and progress is being made in that avenue, however it is still probably like fucking a dead body for most people. The uncanny valley is too large.
However, if you mix VR with deep fakes and advanced dildonics you could create a very realistic and satisfying experience with current technology. Just sayin’…
I tend to be very “conservative” when making predictions about the future, probably because saying ‘the effect will end up being small’ is generally a likely and safe bet. But in this case it could really be that there is a massive shift - pornography did end up having a very big impact, after all, and it does not involve real human-to-human contact. Since I am not much of a consumer in this market, I don’t really have the mindset to predict what customers will like. I am quite curious about what ends up happening, though. I still suspect that synthetic sex will be an ‘additional’ experience and won’t replace many prostitutes.
