Chess champion & artificial intelligence expert David Levy predicts robotic prostitutes will be available as a consumer electronics product by 2050.
I think this would be a great benefit to society, & would cut the global birth rate by say 5%, which would probably do more to fight global warming & competition for natural resources like oil & water, moreso than other initiatives. Also STIs, prostitution, rape, & abortions would prolly also decrease.
I've been telling my homie & virtual reality expert Elchill, that if he were to start a company that applied VR to "erotic applications", he might end up on the Billionaires list. Sex sells, literally.
